LOCATION AND PLACEMENT:
1. This unit should be installed indoors by a qualified serviceman in a non-
freezing, dry environment away from damaging winds and rain. If any
part of the unit becomes frozen, excessive pressure may build up in the
unit which could cause it to burst resulting in possible serious injury to
the operator or bystanders. Normal precautions should be taken so that
excess moisture does not reach the electrical controls or the power unit.
DANGER RISK OF EXPLOSION OR FIRE! DO NOT PLACE UNIT
IN AN AREA WHERE FLAMMABLE GAS VAPORS MAY BE
PRESENT. A SPARK COULD CAUSE AN EXPLOSION OR FIRE!
RISK OF UNIT BURSTING! DO NOT LOCATE THE UNIT IN
FREEZING ENVIRONMENTS!
2. It should be placed in an area away from flammable or combustible material.
These types of material should be kept at least 20 feet away from the unit.
3. Avoid small areas and exhaust fans. Combustion becomes difficult and
carbon monoxide may result in these areas. Allow enough space for
servicing. Some codes will require certain distances from walls and flooring.
Two feet away from the walls should suffice.
4. This unit should only be placed on a level surface. NEVER spray water
directly on the unit.
5. DO NOT place unit in an area:
a. where flammable gas vapors may be present.
b. with insufficient ventilation.
c. where there is evidence of oil or fuel leaks.

1. Installation of this unit should be performed by a qualified serviceman and
all electrical installation must conform to all local, state and national codes,
including NFPA No. 70 (NEC) National Electrical Code. In Canada; Refer
to the CSA C22.1 Canadian Electrical Code Part 1.
2. Ensure electrical supply is identical to the specifications listed on the heater
module data plate.
3. Ensure all connections are secure and covers are replaced.
VENTILATION:
1. Installation of this unit in an indoor or in an enclosed area should be
performed by a qualified serviceman and all venting must conform to all
local, state and national codes, including the National Fuel Gas Code ANSI
Z223.1/NFPA No. 54. In Canada; Refer to the CSA B149.1 Gas Installation
Code. The burner exhaust should be stacked to the outside atmosphere
and a draft diverter should be installed as well.
NOTE: There should be no more than 6500 BTU per square inch of flue.
2. A draft diverter must be installed above the exhaust outlet. This diverter
breaks the chimney effect and enhances the draft through the burner for
a more efficient flame. It also helps prevent cold air down drafts from
freezing the heat exchanger.
3. Install the recommended flue pipe per local, state and national codes,
