VENTILATION AND FIRE SAFETY SYSTEMS
Your new gas appliance must have proper ventilation to function safely and properly. Exhaust gas
temperatures can reach as high as 1000°F (538 °C). Therefore, it is very important to install a fire safety
system. Your ventilation system should be designed to allow for easy cleaning. Frequent cleaning of the
ventilation system and the appliance will reduce the chances of fire. Table 1-2 provides a list of reference
documents that provide guidance on ventilation and fire safety systems. This table is not necessarily
complete. Additional information can be obtained from CSA International, 8501 East Pleasant Valley Rd.,
Cleveland, OH 44131.
Excessive ventilation causes drafts, which will interfere with the proper operation of the pilot and the
burner. Leave at least 18 inches of open space between the appliance’s flue vent opening and the intake of
the exhaust hood.
CAUTION
Ensure that our ventilation system does not cause a down draft at the appliance’s
flue opening. Down drafts will not allow the appliance to exhaust properly and will
cause overheating which may cause permanent damage. Damage caused by down
drafts will not be covered under equipment warranty. NEVER allow anything to
obstruct the flow of combustibles or ventilation exiting the appliance flue. DO NOT
put anything on the top of the flue area.
NOTICE
NEVER connect the blower directly to the flue opening(s). The direct flow of air will
cause poor temperature recovery, poor ignition, and inefficient operation of the
appliance and could extinguish the pilot(s).
GAS LINE REQUIREMENTS
A properly installed gas supply system will deliver adequate pressure (7 to 8 inches w.c. for natural gas,
11 to 12 inches w.c. for propane) to all appliances connected to the line, operating at full demand.
INSTALLATION
The installation of this appliance MUST conform to local codes. In the absence of local codes, the
installation must conform to the National Fuel Gas Code, ANSI Z223.1; Natural Gas Installation Code,
CAN/CGA-B149.1; or Propane Installation Code, CAN/CGA-B149.2 as applicable.
A. Uncrate and put the appliance into place.
B. FOR INSTALLATION ON LEGS: A set of 4” legs is shipped with the appliance (unless appliance
was specifically ordered without legs) . A threaded receptacle is located near each corner of the
underside of the base of the appliance. Each leg has a similar mating thread. Raise appliance
sufficiently to allow legs to be screwed tightly into receptacles. Level the unit by adjusting bottom feet
of legs with a pair of water pump pliers.
CAUTION
The appliance must be level to perform properly. Failure to level unit may result in
improper combustion and performance of the appliance.
