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.

CLEARANCES

Minimum clearances to combustibles are:

Top of Spacers 0" min.

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).

4. Feed exible gas line through one of three

gas line conduit sleeves and repack insu-

lation to cover any openings. Prepare the

incoming gas line with Teon tape or pipe

joint compound and hookup incoming gas

line to exible gas line.

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

tting.

WARNING: When nishing

appliance, do not overlap com-

bustible material onto the black

front face. Brick, tile, or other

noncombustible materials may

be applied to the face provided

that any gap is between the

material used and the face is

caulked with a noncombustible

caulking.

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.

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 ac-
