IMPORTANT:Readthisowner’s

manualcarefullyandcompletely

before trying to assemble, op-

erate or service this replace.

Improper use of this replace

cancauseseriousinjuryordeath

from burns, re, explosions,

electrical shock and carbon

monoxidepoisoning.

DANGER:Carbonmonoxide

poisoningmayleadtodeath!

This replace is a vented product. This re-

place will not produce any gas leakage into

your home if properly installed. This replace

must be properly installed by a qualified

service person. If this unit is not properly

installed by a qualied service person, gas

leakage can occur.

CarbonMonoxidePoisoning:Early signs of

carbon monoxide poisoning resemble the u,

with headaches, dizziness or nausea. If you

have these signs, the replace may not have

been installed properly. Getfreshairatonce!

Have replace inspected and serviced by a

qualied service person. Some people are

more affected by carbon monoxide than oth-

ers. These include pregnant women, people

with heart or lung disease or anemia, those

under the inuence of alcohol and those at

high altitudes.

Propane/LP and Natural Gas: Both are odor-

less. An odor-making agent is added to each

of these gases. The odor helps you detect a

gas leak. However, the odor added to these

gases can fade. Gas may be present even

though no odor exists.

Make certain you read and understand all

warnings. Keep this manual for reference. It

is your guide to safe and proper operation of

this replace.

WARNING: Any change to

thisreplaceoritscontrolscan

bedangerous.

SELECTING LOCATION

To determine the safest and most efcient

location for your appliance, you must take into

consideration the following guidelines:

1. The location must allow for proper clear-

ances (see Clearances).

2. Consider a location where heat output

would not be affected by drafts, air con-

ditioning ducts, windows, or doors.

3. A location that avoids the cutting of joists

or roof rafters will make installation easier.

Figure 2 shows a plan view of a few com-

mon locations.

Flush installations are recommended where

living space is limited or at a premium, and

since the space required to enclose the ap-

pliance would be located beyond an outside

wall, this would also reduce the cutting of

joists, roof rafters, and such. Check local

codes for any restrictions.

Projected installations can extend any

distance into the room. A projection may

be ideal for a new addition on an existing,

nished wall.

Corner installations make use of space

that may not normally be used and provides

a wider and more efcient range for radiant

heat transference.

Internal wall installations provide a discreet

option for room separation and can also be

ideal as an addition to an existing wall.

FRAMING

1. Frame appliance enclosure as illustrated

in Figures 7 and 8.

Note: If a wall covering is used to line the

enclosure, then all measurements must

be from the surface of the covering.

2. Place the appliance into the framing and

secure it.

Note: If appliance is to be raised above

oor level, a platform must be built to

support the appliance.

3. Install the supply line to the appliance

using a 1/2" NPT black iron gas line ter-

minating 2 5/16" above the bottom of the

appliance. The gas line may be installed

from either side or from the rear of the

appliance (see Figure 18, page 13).

joint compound and hookup incoming gas

line to exible gas line.

Note: If 1/2" NPT black iron pipe does not

mate with tting at the end of exible gas

line, remove tting and replace with a 37

degree are 3/4"-12, 1/2" NPT (female)

VENTING INSTALLATION

A B-type venting system must be connected

to the appliance for venting to the outside of

the building.

The following section is provided as a guide

to a standard B-type vent installation.

Standing codes requirements concerning B-

type vent installations may vary within your

state, province or local codes jurisdiction.

Therefore, it is recommended that you check

with your local building codes for specic

requirements or in absence of local codes,

follow Section 7.0 of the current National Fuel

Gas Code NFPA No. 54/ANSI Z223.1 and in

Canada with CAN/CSA B149 for Category I

Systems Using Double Wall B-1 Vent Pipe.

This gas appliance must be vented to the

outdoors only and may not be terminated into

an attic space or into a chimney ue servicing

a solid fuel burning appliance.

This appliance may be vented through a

manufactured chimney system or a masonry

chimney using a B-vent adapter or a chim-

ney liner system if all are listed, inspected

and approved by local codes and/or building

authorities.

The examples shown in Figure 9, page 10

are typical of most B-vent installations and

code practices.

EXAMPLE 3

Example 1 shows the minimum allowable

system height and lateral offset for a 60° or

greater inclination. Code species that offsets

at 60° or greater are considered horizontal

and must follow the 75% rule for lateral to

total vertical system height. Codes also al-

lows only one offset in the total system when

at 60° or greater. The total vertical height in

this example represents the minimum height

of 8 feet and therefore the allowable lateral

is 6 feet when the 75% rule applies. If the

lateral length must exceed 75% then the

system must be sized in accordance with the

Category I venting tables.

Example 2 shows a multiple offset each at 45°

of inclination. Multiple offsets are permitted if

they do not exceed 45° of inclination. The total

lengths of the two offsets are not required to

meet the 75% allowable rule.

Example 3 shows a single offset at 45° of

inclination and therefore the lateral length at

10 feet of offset does not have to meet the

75% rule.

In each case the offsets must be supported

and restops must be positioned wherever

the vent must pass through a suboor, ceil-

ing joist or an attic overhang. The vent pipe

must terminate vertically into a listed type vent

cap and extend a sufcient height through

an approved roof ashing, roof jack or a roof

thimble. At all points the listed clearances

must be maintained.

Vent terminations must be located in accor-

No. 54 or CAN/CSA B149. These rules apply

to vents at 12" diameter or less and require a

minimum height in accordance with the roof

pitch and a minimum of 8 feet distance from a

vertical wall or obstruction (see Figure 10).

If venting horizontally through a side wall be-

comes necessary, a listed thimble approved

for use with B-type vent must be used. Check

with your local codes before venting through

a side wall.
