wastewater codes;
b. In the absence of local building codes refer to:
•
In the USA- The National Fuel Gas Code, NFPA
54/ANSI Z223.1
•
In Canada- The Natural Gas and Propane Installation
Code, CSA B149.1
c. National codes, such as OSHA in the USA.

parts, please order according to the replacement parts list. The
manufacturer reserves the right to substitute other authorized
controls as replacements.
7. Do not adjust or alter the fan blade or motor operating speed.
8. The heater must be installed to maintain normal room
temperatures. Operating temperatures below 50°F (10°C)
can result in premature failure of the heater and cause unsafe
operation. Thermostats with a minimum operating temperature
of 50°F (10°C) should be installed.
9.
The heater cannot be operated in temperatures above 90°F
(32°C). Operating the heater above 90°F (32°C) can cause failure
of the heater and electrical components and result in unsafe
operation.
10. Do not install the heater outdoors. Avoid water spray and
dripping of water onto the heater.
11. High humidity and high salt areas can damage the heater and
reduce the life of the heater resulting in unsafe operation.
12. Verify that the heater can be safely vented to the outdoors
according to these instructions and local/national codes.
13. Do not install units in locations where the flue products can be
drawn into adjacent building openings such as windows, fresh air
intakes and doors.
14. Maintain the minimum clearances/distance to combustible
materials and recommended service clearances shown in Figure 2
and Table 3.
15. All appliances and machines generate noise. This heater
generates noise and vibration from the fan, motors and
combustion processes. This noise could be considered a nuisance
near quiet zones such as offices.
16.
Utility heaters must be installed at least 18” (46 cm) above the
floor in garages.
17. The heater should be installed so that air can move freely to all
air openings on the heater. This includes combustion air and air
for the fan.
