Use and Care Manual
19
1. Vent system must be installed in accordance with local codes, or, in absence of local codes, the National Fuel Gas Code, ANSI Z223.1 / NFPA 54
and/or CSA B149.1, Natural Gas and Propane Installation Code.
2. For installation in Canada, installer supplied plastic vent piping must comply with CAN/CSA B149.1 and be certied to the Standard for Type BH
Gas Venting Systems, ULC-S636. Components of this listed system must not be interchanged with other vent systems or unlisted pipes or ttings.
All plastic components and specied primers and glues must be from a single system manufacturer and must not be intermixed with another
system manufacturer’s products. Clean and dry all applicable surfaces before applying cement.
3. This appliance is designed to be installed in a power vent (using indoor air for combustion and vented to the outdoors) type, or as a direct vent
(sealed combustion) type. In power vent installations, indoor air is used for combustion and exhaust gases are vented directly to the outdoors
through a sealed exhaust vent piped through the wall or roof. In direct vent installations, combustion air must be supplied directly from the outdoors
to the burner, and the ue (exhaust) gases should be vented directly to the outdoors through the wall or roof.
4. This appliance uses 2" or 3" diameter pipe for exhaust vent and intake pipe. It is important to ensure an airtight seal from the appliance collar to
the vent terminations. See Table 10 for a list of Approved Vent Materials.
5. Do not install venting system components on the exterior of the building except as specically required by these instructions.
• Vent terminals must be at least 1 foot from any door, window, or gravity inlet into the building.
• Maintain the correct clearance and orientation between the exhaust vent and intake pipe terminals.
• The exhaust vent and air intake terminals must be at the same height and their center lines must be spaced apart 1 foot minimum.
• The bottom of the exhaust vent and intake pipe terminals must be at least 1 foot above the normal snow accumulation level. In no case should
these terminals be installed less than 1 foot above normal snow accumulation level.
• Do not install the exhaust vent terminals directly above windows or doors.
• Intake pipe terminal must not terminate in areas that might contain combustion air contaminates, such as near swimming pools.
• For sidewall venting, the minimum horizontal distance between adjacent exhaust vent terminations is 1 foot. It is recommended this distance be
greater than 1 foot to better avoid frost damage to building surfaces.
• For roof venting, minimum horizontal distance between any adjacent exhaust vent termination is 1 foot.
• If the exhaust vent is to be terminated in a walled off area (such as a roof with a parapet wall), ensure the exhaust vent terminates a minimum of
10' from nearest wall and extends level with or above the top of the wall. This will ensure ue gas does not get trapped and possibly recirculated
into the intake air pipe, which could contaminate the combustion air.
• Do not locate vent over public walkways, driveways, or parking lots. Condensate could drip and freeze, resulting in a slip hazard or damage to
vehicles and machinery.
▪ A. INTAKE PIPE AND EXHAUST VENT GUIDELINES
WARNING
DO NOT mix vent systems or materials unless specically told to do so in this manual.
DO NOT thermally insulate the exhaust vent or intake pipes.
DO NOT use an electric damper, vent damper, or draft hood with this appliance.
DO NOT locate the exhaust vent or intake pipe terminations where exposed to prevailing winds.
Moisture will be produced by the exhaust vent. Take precautions when determining exhaust vent termination. Moisture may fall from the vent
termination to the ground and turn to ice in freezing conditions. Moisture or ice can produce a hazardous condition.
Exhaust condensate is acidic, and could deteriorate the surface below the exhaust vent termination. Ensure this surface is in good repair (sealed,
painted, etc.) to prevent deterioration.
Pitch the exhaust vent pipe ¼" per foot back to the appliance. This ensures that condensate in the exhaust vent returns to the appliance and
drains properly.
Failure to follow these instructions could result in property damage, severe personal injury, or death.
PART 5 –VENTING
Vent this appliance in accordance with these instructions. Failure to do so will result in property damage, severe personal injury, or death.
