INITIAL START-UP

IMPORTANT NOTICE: This heater is not to be used as a construction heater to supply heat to an
unfinished building during the finishing phases of Construction. This practice exposes the unit to an
abnormally corrosive atmosphere from sources such as paint, varnish and adhesives, which can lead
to premature radiant tube exchanger or vent failure. The practice also allows foreign materials such as
sawdust or sheet rock dust to enter the combustion blower, burner, heat exchanger and vent system,
resulting in shorter life of the unit.
Use of the heater as a construction heater will void the warranty.
Procedure:
a) Make sure gas is turned on.
b) Check for any possible blockages in combustion air intake and exhaust areas of unit.
c) Make sure that venting material is properly fastened to the unit.
d) Make sure all options are attached securely.
e) Make sure electricity is on to unit.
f) Turn thermostat up past room temperature.
g) Check the flame port to see flame has established,
h) If flame is not established, turn the thermostat down for 5 seconds then turn back up or interrupt
electrical supply to unit for 5 seconds, and allow unit to try again.
i) Verify that the manifold pressure (outlet pressure tap) on the gas valve is the same pressure as
stated on the rating plate of the unit. Use a manometer that measures inches of water column for
this procedure. If adjustment is required, remove the cap-screw from the pressure regulator
housing. Adjust the white pressure regulator adjusting screw clockwise (in) to increase pressure,
counterclockwise (out) to reduce pressure. Replace cap-screw. After measurement has been
taken, replace pipe plug in outlet pressure tap. Check for leaks. (see pages 3, 4 & 59)
j) Verify gas input rate. (see page 48)
NOTE: Oil smoke might appear off of exchanger tube after it heats up for initial firing. Do not be alarmed.
The smoke is just a small amount of oil on the surface of the tube from manufacturing. If smoke is excessive,
open door and 'air out' the building until smoke is removed.
NOTE: Heater will have a higher heat output at the burner end as compared to the exhaust end. This is
normal.
NOTE: A small amount of condensation may occur from the heater when it starts the heating cycle. The
condensation will stop once the heater warms up. Make sure venting is sealed.
WARNING:
DO NOT ATTEMPT TO IGNITE HEATER BY HAND!!
