Ventilation
1. It is required that areas above the heater be
properly vented to allow for necessary combustion
air and removal of combustion gases.
2. Heaters shall be provided with natural or
mechanical means to supply and exhaust at least
4 cfm per 1,000 BTU per hour of heater input.
Exhaust openings for removing the flue products
shall be above the level of the heaters.
3. Heater ventilation must comply with state and local
codes. Never use heater in a fully enclosed
area.
Fire Sprinklers
Fire Sprinklers must be located at an appropriate
distance from each heater to avoid accidental activation of
the sprinkler. Ethylene glycol or propylene glycol must
never be used in fire sprinkler systems where heaters are
present as these substances may become flammable
when heated. A fire sprinkler professional must be
consulted when heaters are installed where fire sprinklers
are present to insure that heaters and the fire sprinkler
system are properly integrated. Specific guidelines can be
found in NFPA 13 regarding design and specifications for
Fire Sprinkler Systems near heaters.
Initial Start-
Up Procedure
(Read entire Procedure First)
1. Before turning ON your new heater make sure:
a. Heater is securely mounted and clearances from
combustible materials have been observed (see
Clearances – page 7);
b. Tip angle of heater does not exceed 30 degrees
(see Correct Mounting – page 12);
c. Gas line is properly connected and there are no
leaks (see Gas Piping – page 8);
d. Make sure 24 VAC is properly connected to the
heater. Applying 120 VAC to the heater will
damage the switch and other heater controls
2. Start Heater;
a. Turn ON manual gas valve.
b. Set switch to the high setting for the first 5
minutes.
c. If heater locks out, switch to OFF to RESET
Heater and repeat start up sequence.
d. If the heater locks out several times there may still
be air in the gas line.
NOTE: Some white smoke may appear
during or just after the initial start-up of the
heater. White smoke will dissipate with
proceeding use. This is normal due to some
residual lubrication on a new heater
