GAS CONNECTION
A qualified gas appliance installer must connect the heater to the
gas supply. Consult all local codes.
NOTICE
Use new black iron or steel pipe only. Internally tinned copper tubing can be
used in some areas when permitted by local codes. Only use pipe of 1/2" or
greater diameter to allow full gas volume to heater. Excessive pressure loss will
occur if the pipe is too small.
A manual shutoff valve, union and plugged 1/8" NPT pressure tapping point
must be installed upstream of the heater (FIGURE 6).
CAUTION
A sediment trap must be installed upstream of the heater to prevent moisture
and contaminants from passing through the pipe to the heater controls and
burners. Failure to do so could prevent the heater from operating reliably
(FIGURE 8).
IMPORTANT: Loosen the pipe adapter
on the flex tube before installing to the
system piping.
Diagram Nº 9. Gas Connection
CHECK GAS TYPE: The gas supply must be the same as stated on heater's rating plate. If the
gas supply is different, DO NOT INSTALL the heater. Contact your dealer for the correct model.
Connecting directly to an unregulated propane/LPG tank can
cause an explosion.
WARNING
Reattach the front to the unit. Use the same screws removed in the instructions on page 5. Reinstall
the control knob.

OPERATING INSTRUCTIONS
FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING: If you do not follow these instructions exactly, a fire or explosion
may result causing property damage, personal injury or loss of life.
This appliance has a pilot which can be light with the equipped piezo ignitor. When lighting the pilot, follow these
A.
instructions exactly.
BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some
B.
gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not attempt to light any appliance.
• Do not touch any electric switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire department.
Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by
C.
hand, don't try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or
explosion.
Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect
D.
the appliance and to replace any part of the control system and any gas control which has been under water.
LIGHTING INSTRUCTIONS
STOP! Read the safety information above on this page.
1.
Press the knob lightly and turn clockwise to the “OFF” position.
2.
Wait five (5) minutes to clear out any gas. If you then smell gas, STOP! Follow
3.
“B” in the safety information above on this page. If you don’t smell gas, go to the
next step.
Find the pilot by looking through the viewing window on the front of the unit.
4.
Press the knob down lightly and turn counterclockwise to the “Pilot”.
5.
Press again downwards.
Press the Piezo Ignition button to light the pilot. Repeat this operation with the
6.
knob pressed down until the pilot has lit. When the pilot lights, continue holding
pressure for another 10 seconds. Release the knob. If the pilot goes out, repeat
the process 1 through 6.
If the knob does not pop up when released, stop and immediately call your ser-
!
vice technician or gas supplier.
If the pilot will not stay lit after several tries, turn the gas control knob to OFF and
!
call your service technician or gas supplier.
Press down and turning the control knob counterclockwise to the
7.
desired temperature. The temperature can be regulated between HI and LO
capacity, according to the indicated scale marked on the knob.
When the heater is first started after installation or if the heater has not been used for a long period of time, there is a
normal delay of gas from the gas supply through the gas control on the heater. In this case, maintain pressure on the knob
at the “Pilot” position for 30-40 seconds and then try the piezo lighter.
TURN OFF GAS TO APPLIANCE
When the heater is not to be in use for a long period of time or for servicing, turn the control knob clockwise to
the OFF position and close the main gas supply valve.

MAINTENANCE INSTRUCTIONS
As with all fuel burning appliances, it is important to conduct periodic maintenance functions that will allow for continued safe, efficient operation of the unit. We suggest that before every heating season, or at least once a year, conduct
the following minimum service functions.
STEP 1: The gas supply should be turned OFF at the shutoff valve in the supply line leading to the appliance or at the
gas source. The gas to the unit should then be disconnected so the unit can be removed from the wall.
STEP 2: Remove the front cover by removing the control knob and the two(2) screws on the top of the front. Then slide
the front upwards.
STEP 3: Carefully examine the interior of the vent pipe. If you notice any blockages or obstruction that was not part of
the unit when it was installed. Clean the pipes and prepare them for reattachment to the unit.
The vent system should be inspected periodically, or at least once a year and cleaned if necessary. If removal of the
venting is required, follow the instructions in the “Ventilation Installation” section of this manual for reassembly.
STEP 4: Look inside the openings of the rear of the unit and check for foreign materials. Remove any objects which may
block or obstruct the free flow of combustion and ventilation air.
STEP 5: Visually check the pilot and the main burner for signs of excessive dirt or debris through the heat exchanger
front glass. If you find any of these, follow the directions below to reach the components to clean, otherwise continue to the
next step.
To Remove Pilot: Find the pilot. Loosen the head of thermocouple, disconnect the pilot gas supply line, (only on the side
of the pilot, not on the valve side). Remove the two(2) M4 screws that hold the pilot in place. Clean with a vacuum cleaner
or use a can of compressed air.
To Remove Burner: Loosen the gas line from the burner (on the right side of the unit). On the left side of the unit,
unscrew the nut that holds the burner in place. Then remove the burner. Clean with a vacuum cleaner or use a can of
compressed air. Note: You can remove the main burner-pilot assembly if you don’t unscrew the M4 screws that hold the
pilot to the burner.
Before reinstalling the assembly, check the ceramic fiber sealing gasket. If it is damaged or worn, replace with new gasket
available from your dealer.
STEP 6: Reassembly the unit back to its original state and mount the unit to the wall. Properly reassemble and reseal
the vent-air intake system.
STEP 7: Reconnect the gas supply and check for leaks using a soapy water solution. Bubbles on any of the joints
indicate a leak is present and must be repaired. Turn off the gas when making such repairs. Check to make sure that the
piezo ignitor still lights the pilot.
STEP 8:
12)
Note: After maintenance, the first few minutes of the heater operation will probably have some yellowish flying traces in
the flame due to the burning of particles left behind during the cleaning operation.
** Liquid Propane will have some evidence of yellow tips on the flame.
While the main burner is ON, Check the flames to verify that they are burning a clean blue color. (See Diagrams 10-
Any safety screen or guard removed for servicing an appliance must be replaced prior to
operating the appliance
Before completing your periodic maintenance check, ensure the heater area is kept clean and
free from combustible materials, gasoline and other flammable vapors and liquids. Also,
check to see that the flow of combustion and ventilation air around the vent cap on the outside
of the structure is not obstructed.
