WARNING
Improper installation, adjustment, alteration, service
or maintenance can cause property damage, injury
or death. Read the installation, operating and
maintenance instructions thoroughly before
installing or servicing this equipment.
FOR YOUR SAFETY
Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other
appliance. If you smell gas:
1. Open windows
2. Don’t touch electrical switches
3. Extinguish any open flame
4. Immediately call your gas supplier
OWNER
Retain this manual for reference.
INSTALLER
Read and thoroughly understand these Instructions
before attempting any installation
CAUTION: FIRE OR EXPLOSION HAZARD
Maintain clearance to combustible constructions as
further specified in this manual. Failure to do so
could result in a serious fire hazard. Heaters should
not be located in hazardous atmospheres containing
flammable vapors or combustible dusts. Signs
should be provided in storage areas specifying
maximum safe stacking height.
CAUTION: MECHANCIAL HAZARD
This equipment is designed and approved for indoor
use only.
CAUTION: FIRE OR EXPLOSION HAZARD
This heater is equipped with an automatic ignition
device. Do not attempt to light the burner by hand.
Failure to comply could result in a serious fire and
personal injury hazard.
CAUTION: MECHANCIAL HAZARD
Do not use high pressure (above 1/2psi) to test the
gas supply system with the burners connected,
doing so could result in damage to the burner and
its control components requiring replacement.
Do not install equipment in atmospheres containing
halogenated hydrocarbons or other corrosive
chemicals, doing so may lead to premature
equipment failure and invalidation of the warranty.
CAUTION: SERVICE LIFE RISK
Due to continuous product innovations, we reserve the right to change product specifications without due notice.

WARNING
◊ For your safety, shut off the main gas valve, and disconnect all electrical supply to the High
Intensity Unit.
◊ Ensure the heaters are properly grounded.
◊ Perform all work in accordance with local codes or the National Electric Code ANSI/NFPA 70 or
Canadian Electrical Code CSA C22.1.
◊ Connect the Igniter cable, Flame sensor wire and the ground wire as illustrated below.
◊ This appliance is equipped with a safety control system designed to shut the burner off in the
event of inadequate gas pressures.
