Operating Instructions and Owner’s ManualMr. Heater | Gas-Fired Low-Intensity Infrared Heater
Operation of the Heater
CHILDERN AND ADULTS SHOULD BE ALERTED TO THE HAZARDS OF
HIGH SURFACE TEMPERATURES AND SHOULD STAY AWAY TO AVOID
BURNS OR CLOTHING IGNITION.
YOUNG CHILDERN SHOULD BE CAREFULLY SUPERVISED WHEN
THEY ARE IN THE SAME SPACE AS THE HEATER.
CLOTHING OR OTHER FLAMMABLE MATERALS SHOULD NOT BE
HUNG FROM THE HEATER, OR PLACED ON OR NEAR THE HEATER.
ANY GUARD OR OTHER PROTECTIVE DEVICE REMOVED FOR
SURVICING THE HEATER MUST BE REPLACED PRIOR TO OPERATING
THE HEATER.
INSTALLATION AND REPAIR SHOULD BE DONE BY A QUALIFIED
SERVICE PERSON. THE HEATER SHOULD BE INSPECTED BEFORE
USE AT LEAST ANNUALLY BY A QUALIFIED SERVICE PERSON.
MORE FREQUENT CLEANING MAY BE REQUIRED AS NECESSARY.
IT IS IMPERATIVE THAT THE CONTROL COMPARTMENT, AIR
PASSAGEWAYS AND BURNER (S) OF THE HEATER ARE KEPT CLEAN.
1. Turn the thermostat up. When the thermostat calls for heat, the
blower motor will energize.
2. When the motor approaches nominal running speed, the air
proving switch closes and activates the ignition module which in
turn initiates the purge.
3. The ignition module then energizes the spark igniter.
4. When sparking begins, the gas valve is energized.
5. If a ame is detected, the gas valve remains open. When the
call for heat is satised, and the system control mechanism de-
energizes, the burner line voltage supply and the gas valve are
turned off.
6. If no ame is detected, the gas valve is closed, and a purge
period begins. After the purge period, the ignition module
energizes the spark igniter and the gas valve. If a ame is still not
established, a third and nal purge/ignition sequence is begun.
After three failed attempts, the system control mechanism will
lock out for a period of one hour, or until the unit is reset. Reset
is accomplished by removing power from the heater for at least
ve seconds.
7. With a three-try module, when the ame is established and then
lost on the rst or second trial, the gas valve will automatically
turn off. A purge and trial for ignition will then occur.
8. Periodic visual check of burner ame while unit is in operation
through sight glass in bottom of unit.
Section 6 MAINTENANCE
Pre-Season Maintenance
Heater area to be kept clear and free form combustible materials,
gasoline and other ammable vapors and liquids.
Do not use this appliance if any part has been under water.
Immediately call a qualied service technician to inspect the
appliance and replace any part of the control system and any gas
control, which has been under water.
(CAUTION) Label all wires prior to disconnection when servicing
controls. wiring errors can cause improper and dangerous operation.
For best performance, the following maintenance procedures should
be performed by a qualied service agency before each heating
season:
1. A qualied service agency should be contacted for service other
than routine maintenance.
WARNING Turn off the gas and electrical supplies to
the heater before performing any service or maintenance.
Failure to observe this warning will cause death, injury or
property damage.

2. Check condition of blower scroll and motor. Dirt and dust may
be blown out with compressed air, or a vacuum cleaner may be
used.
3. Check the condition of the burner cup. Carefully remove any dust
or debris form inside burner cup.
4. Inspect the igniter. Replace igniter if there is excessive carbon
residue, erosion of electrodes of other defects.
5. Check to see that the burner observation window is clean and
free of cracks or holes. Clean or replace as required.
6. Check the ue pipe for soot, dirt or obstructions. The ow of
combustion and ventilation air should not be obstructed. After
cleaning as necessary, re-attach the ue pipe to the heater.
7. Outside surfaces of heater reector may be cleaned by wiping
with a damp cloth.
8. Check vent terminal and outside air inlet to see that they have
not become blocked during the non-heating season. If either
pipe is restricted, the air switch won’t close, resulting in a no-
heat situation.
9. Verify proper operation after service.
