OUTSIDE VENT COVER REMOVAL

The heater is supplied from the factory with a built-in

stackless outside vent for outdoor installation. Remove the

outside vent cover for outdoor shelter installation.

VERTICAL VENTING - NEGATIVE PRESSURE

(See Figures 11 and 12)

Vent the heater vertically in a negative pressure (positive draft)

system in accordance with the National Fuel Gas Code, ANSI

Z223.1/NFPA 54 and/or CSA B149.1, National Gas and

Propane Installation Codes, and local codes. Type “B”

Double-wall vent connector is recommended; however sin-

gle-wall pipe is allowed by the National Fuel Gas Code in

some circumstances. Consult your local code official for

detailed information. Do not use a draft hood with this heater.

To connect a negative pressure metal gas vent to the

heater, order the appropriate Metal Flue Collar from the

chart below:

1. See Table 3, below, to determine allowable vent sizes

for your heater.

NOTICE: Table 3 is for installations in which the total later-

al vent length (that is, the horizontal distance from the flue

collar to the main vertical portion of the vent) is less than

1/2 the total vent height (the vertical distance from the flue

collar to the vent termination) and which have three or less

elbows in the system. For venting systems which do not

meet these conditions, consult the National Fuel Gas

Code, ANSI Z223.1 (U.S.), or the standards CSA B149.1

and B149.2 (Canada).

2. Install the metal Flue Collar in the Vent Body of the

heater (located under the outside vent cover). Fasten the

metal Flue Collar to the Vent Body with two #10 sheet

metal screws. Use UltraCopper

silicone RTV to seal the

Flue Collar to the Vent Body. Before connecting the

metal Flue Collar to the Vent Body, wet a clean cloth or

paper towel with isopropyl alcohol (rubbing alcohol) and

vigorously wipe the socket of the Vent Body.

Immediately wipe the cleaned surfaces dry with a clean

cloth or paper towel. Repeat for the exterior of the 4”

end of the metal Flue Collar. Attach the metal Flue Collar

to the Vent Body using the RTV supplied with the kit, fol-

lowing the vent manufacturer’s instructions (included

with kit). Do not use a draft hood with this heater.

3. Attach the vent pipe to the metal Flue Collar with

sheet-metal screws.

Risk of fire or asphyxiation if vent is not

assembled according to manufacturer’s instructions or if

vent parts from different manufacturers are mixed. Vent

parts from different manufacturers ARE NOT interchange-

able. Mixing parts from more than one manufacturer may

cause leaks or damage to vent. When assembling a vent,

pick one manufacturer and be sure that all vent parts come

from that manufacturer and are specified by the manufac-

turer for your system. Follow manufacturer’s instructions,

local code requirements, National Fuel Gas Code require-

ments (U.S.) or standards CSA B149.1 and B149.2

(Canada) carefully during assembly and installation.

4. Install vent pipe so that it can expand and contract

freely as the temperature changes. Support the vent pipe

according to applicable codes and the vent manufactur-

er’s instructions. Pipe support must allow the vent pipe

free movement out and back, from side to side, or up

and down as necessary, without putting a strain on the

heater or vent body. Slope horizontal pipe runs up from

the heater at least 1/4” per foot (2cm per meter). Install

Listed condensate drains at low points where conden-

sate might collect. Plumb condensate drains to a drain

through hard piping or high-temperature tubing such as

silicone rubber or EPDM rubber – do not use vinyl or

other low temperature tubing. Follow drain manufactur-

er’s installation instructions.
