WARNINGS

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 & ensure available for service.

Improper installation, adjustment, alteration, service

or maintenance can cause injury, death or property

damage.

Read the installation, operation and service

instructions thoroughly before installing or servicing

this equipment.

INSTALLER

Provide Manual to Owner upon completion of

installation!

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 expands and contracts with each

operating cycle. The gas connection, suspension

hardware and the installation itself must safely allow

this movement. Failure to do so could result in

serious fire or explosion hazard.

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 1/2 psi) 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.

Additionally, it is recommended that the equipment

be installed with a slope downward and away from

the burner of ¼" (6mm) in 10' (3m) to allow start-up

condensate drainage.

CAUTION: SERVICE LIFE RISK

Due to continuous product innovations, we reserve the right to change product specifications without due notice.
