OPERATING INSTRUCTIONS
1. WARNING: If you do not follow these instructions exactly, a fire
or explosion may result with property damage, per sonal injury
or loss of life.
2. Smell all around the appliance area for gas. If the appliance
uses L.P. (bottled) gas, also be sure to smell next to the floor
because L.P. gas is heavier than air.
3. WARNING: If you smell gas, immediately shut off the manual
valve in the gas piping to the appliance. Don't touch any elec-
trical switch or use the phone. Leave the building and call your
gas supplier. If he cannot be reached, call the fire department.
4. WARNING: Do not force the gas control knob on the appliance.
Use only your hand to push down and/or to turn the gas control
knob. Never use any tools. If the gas control knob will not
operate by hand, the control should be replaced by a qualified
service technician. Force or attempted repair may result in fire
or explosion.
5. WARNING: The gas control must be replaced if it has been
exposed to water.
SERVICE INSTRUCTIONS
CAUTION: If control has been exposed to water in any way, it must be
replaced. If gas valve fails to shut off, do not turn off electrical power.
Turn off gas supply allowing fan or circulating pump (if so equipped) to
continue running until system has cooled. Replace control.
WARNING
Servicing of gas controls, appliance and systems must
be per formed by qualified service personnel only.
PRESSURE REGULATOR ADJUSTMENTS
Adjustment of the pressure regulator is not normally necessary since
it is preset at the factory. However, field adjustment may be accom-
plished as follows:
NOTE: Manometer attachment may be accomplished at pressure tap
plug, above control outlet, as shown in figure to the right. If using inlet
pressure tap to measure incoming pressure. See drawing on first page.
1. Manometer or gauge attachment may be accomplished at pres sure
tap plug (D).
2. Remove regulator adjustment screw cap (top of control - A).
3. With small screwdriver, rotate adjustment screw (B) "clockwise" to
increase, or "counterclockwise" to decrease pressure to comply with
manufacturer's specifications.
4. Replace regulator adjustment screw cap (A).
REGULATOR CONVERSION
CAUTION: Main burner and pilot orifices must be changed when regu-
lator is converted from one type of gas to another.
1. Turn off gas and electricity to appliance.
2. Remove slotted cap (A), adjusting screw (B), and natural gas spring -
not color coded - (C), from control.
3. Install new L.P. spring - color coded with a black strip.
4. Install new adjusting screw (B).
5. Attach manometer or pressure gauge at the outlet pressure tap.
CAUTION
1. Turn wall thermostat to its lowest setting. Remove burner access
panel(s).
Selector arm must only be operated by hand (see below). DO NOT
use pliers, wrenches or other tools to operate the arm. The selector
arm cannot be moved into the "Off" position without first depress-
ing the lever to the "On" position.
2. Move selector arm to the "Off" position. (See figure 1.)
3. WARNING: Wait at least 5 minutes to allow any gas in the
combustion
chamber to vent. If you then smell gas in the appliance area or near
the floor, STOP and follow warning instruc tions to the left. Failure to
do so may result in fire or explosion.
4. Move selector arm to the "On" position, (see figure 2), and set room
thermostat to desired temperature. Allow burner to cycle on and off.
5. Leak test with a soap solution after installing with main burner on.
Coat pipe and tubing joints, gasket, etc. with soap solution. Bubbles
indicate leaks.
6. Replace burner access panel.

6. Turn gas and electricity on.
7. Turn room thermostat to call for heat.
8. With burner on, adjust screw (B) to supply LP. gas to pressure as
recommended by the appliance manufacturer.
9. If adjusting screw (B) reaches its maximum depth (bottoms out)
before recommended pressure setting is reached, turn screw
counterclockwise until pressure drops slightly (approximately 0.1"
W.C.) WARNING: Do not stretch or alter spring.
10. Turn off gas and electricity to appliance.
11. Remove manometer or pressure gauge and reinstall pressure tap
outlet plug (D).
12. Install new red slotted cap in place of (A).
13. Turn gas and electricity on.
14. With burner operating, immediately check all fittings for leaks with
