Installing The Fireplace Shell

The ﬁreplace may be installed in any location that maintains clear-

ances to air conditioning ducts, electrical wiring and plumbing. Safety,

as well as eﬃciency of operation, must be considered when selecting

the ﬁreplace location. Try to select a location that does not interfere

with room traﬃc, has adequate ventilation, and oﬀers an accessible

pathway for Direct Vent installation. Refer to page 4 - B-Vent Installa-

tion for more information.

The ﬁreplace dimensions are shown below:

Figure 1. Fireplace dimensions.

Installing a Shelf Over the Fireplace

When installing a shelf over the top of the ﬁreplace, the minimum al-

lowable clearance from the top of the ﬁreplace to a shelf is 15".(Prop-

er clearance must be maintained around the vent pipes, as speciﬁed

in the clearances section.)

WARNING:

When this appliance is installed directly on carpeting, tile or any

combustible material other than wood ﬂooring, it must be installed

on a metal or wood panel extending the full width and depth of

the appliance.

Clearances

These clearances apply to all dimensions except the framed opening,

where the clearance to combustibles is 0". The C38-BV clearances to

combustible materials are:

Top 15"

Back 0"

Side 0"

Floor 0"

Mantle* 6"

Installing The Gas Line

The gas line must be installed before ﬁnishing the C38-BV Fireplace.

Natural Gas requires a minimum inlet gas supply pressure of 5.5"

W.C. & a manifold pressure of 3.5" W.C. Propane Gas requires a

minimum inlet gas supply pressure of 11" W.C. & a manifold pressure

of 10" W.C. Provision must also be made for a 1/8" N.P.T. plugged

tapping and be accessible for test gauge connection immediately

upstream of the gas supply controls to the appliance. The ﬁreplace

gas connection and the main operating gas valve is located behind

the removable brass trim at the bottom of the unit and need only be

attached to the gas line with an approved ﬁtting, as required by the

applicable installation codes.

• Only use gas shut-oﬀ valves approved for use by the state, province,

region, or governing body, in which the appliance is being installed, or

as required by the applicable installation codes.

• Flexible gas connectors must not exceed 3 feet in length, unless it is

allowable within applicable installation codes.

The appliance and its individual shutoﬀ valve must be disconnected

Installation

Note: After gas line is connected, each appliance connection,

valveand valvetrain mustbe checkedwhileundernormal

operating pressure with either a liquid solution, or leak

detection device, to locate any source of leak. Tighten

any areas where bubbling appears or leak is detected until

bubbling stops completely or leak is no longer detected.

DO NOT use a ﬂame of any kind to test for leaks.

Installing The Remote Switch

The C38-BV's gas valve, located behind the lower brass trim, may be

connected to a wall switch. The valve generates its own power on a

millivolt circuit. Use only low voltage wire, and DO NOT connect

any external power to it.

Refer to Figure 12 for wiring requirements.

Note: The switch location must not exceed 30' from the ﬁreplace.

Figure 5. Gas line access.

from the gas supply piping system during any pressure testing of that

system at test pressures in excess of 1/2 psig (3.5 kPa).

The appliance must be isolated from the gas supply piping system by

closing its individual manual shutoﬀ valve during any pressure testing

of the gas supply piping system at test pressures equal to or less than

1/2 psig (3.5 kPa).

B-Vent Installation

The C38-BV is certiﬁed for use with standard 5" B-Vent and requires

no B-Vent appliance connector. Simply attach the B-Vent to the ﬁre-

place ﬂue collar, and secure it using 1/4" sheet metal screws.

Refer to the current CAN/CGA B-149.1 and .2 or ANSI Z223.1-1988

Gas Installation Code for speciﬁc vent sizing.

Test your B-Vent installation after completion to ensure that no

combustible by-products are spilling from the ﬁreplace open-

ing. This draft test should be performed after a three(3) minute

warm up period. The manufacturer will not be responsible for

any installations with inadequate draw.

CAUTION:

Note: If more than 12 feet of B-vent is used on the vent runs,

use ceiling supports.

Finishing Around the Fireplace

Combustible mantels and mouldings may be safely installed over the

top and on the front of the ﬁreplace provided that they do not project

beyond shaded area shown in Figure 6a. Side wall clearances are 3".

Combustible surrounds may be installed with 3" clearance to the side

of the ﬁreplace as shown in Figure 6b.

Fireplace Facing

When selecting the ﬁnish material for your ﬁreplace, it is important

to remember the following: TRIMS MUST NOT BE OBSTRUCTED

IN ANY WAY - to do so restricts the air supply for the control

compartments and heat exchanger it also prevents access for

servicing controls.

The face of the ﬁreplace may be painted to match the room decor,

provided you use a heat-resistant paint. Decorative facing must not

extend past the ﬁreplace opening at all, because it will interfere with

the access to retainers for removal of glass door.

Installation

Figure 6a. Combustible mantles and facings.

Mantels & Surrounds

NOTE: National Canadian Gas Association mantel test requirements

are for ﬁre hazard prevention to combustible materials.

New technology, to meet consumer and government demands for the

wise use of energy, has prompted us to manufacture many models of

ﬁreplaces which are hot, fuel and energy eﬃcient.

Please be aware; temperatures over the mantel will rise above nor-

mal room temperature and walls above ﬁreplace may be hot to touch.

We recommend careful consideration be given to the eﬀects of

elevated mantel temperatures which may be in excess of product

design, for example: candles, plastic or pictures. This can cause

melting, deformation, discoloration or premature failure of T.V. and

radio components.

Painting:

Special care is recommended by the Master Painters and Decorators

Association, when painting the ﬁreplace surrounds, to select and ap-

ply a quality Alkyd sealer prior to the applying of latex paints. This is

to prevent leaching of water from evaporation and causing a brownish

staining eﬀect to paint over coats.

Burner Adjustment

The C38-BV is equipped with an adjustable burner, allowing you to

raise or lower the ﬂames. To adjust the ﬂames, locate the black knob

marked 'Hi-Lo', in the centre of the gas control valve (See Figure 11).

The front burners are not adjustable.

To raise the ﬂame height, turn the black knob (located behind the

lower trim) counterclockwise.

To lower the ﬂame height, turn clockwise.

Figure 11. 'Hi-Lo' Adjustment on the C38-BV's gas valve.

Cleaning

When the ﬁreplace is ﬁrst activated, there may be some smoking and

a visible ﬁlm may be left on the glass. This is a normal condition, and

is the result of burning of protective coatings on new metal.

Glass must be cleaned periodically to remove any ﬁlm (which is a

normal biproduct of combustion) which may be visible. Film can

easily be removed by removing the door, as shown on page 6-7.

Handle the door carefully, and clean it with non-abrasive glass

cleaners. One of the most eﬀective products is Kel Kem.

Silicone seals on inner door during initial ﬁring will "oﬀ gas", leav-

ing a visual deposit of a white substance on combustion cham-

ber walls. This can easily be removed using normal household

products.

Use a vacuum cleaner or whisk broom to keep the control com-

partment, burner, and ﬁrebox free from dust and lint.

Logs may be cleaned periodically with a vacuum to remove soot

Note: C38-BV-I models (electronic ignition) do not feature

hi/lo adjustment.
