SECTION IV
MAINTENANCE INSTRUCTIONS
Maintenance Instructions for All Calorama/Comfort View Series Heaters:
Step 1 The gas supply should be turned OFF at the shut-off valve in the supply line
leading to the appliance (if supplied), or at the gas source. The gas to the unit should be
disconnected so the unit can be removed from the wall.
Step 2 Remove the front cover, loosen the two (2) bolts on the bottom right and left rear
of the unit 2 or 3 turns (without removing them).
Remove the two (2) screws on top of the unit, pull the front cover forward about an inch
and lift it to take it off.
Step 3 Remove the Calorama/Comfort View unit from the wall mounting plate by
removing the hexagonal nuts (Two (2) nuts for Calorama/Comfort View I or four (4) nuts
for Calorama/Comfort View II and III) inside the back cover.
Step 4 Carefully examine the interior of the vent pipe. If you notice any blockage or
obstruction that was not part of the unit when it was installed, clean the pipes and
prepare them for the reattachment to the unit.
Step 5 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. You will only be able to see a portion of the interior of the unit from this
angle.
IMPORTANT COMFORT VIEW NOTICE: Do not remove the heat exchanger front glass
when carrying out the periodic maintenance check or servicing the unit.
Step 6 Visually check the pilot and the main burner for signs of excessive dirt and debris
through the heat exchanger front glass on Comfort View units or through the pilot
viewing window located at the top right front of the heat exchanger on Calorama units.
If you find any of these, follow the directions below to reach the components to clean,
otherwise continue to Step 7:
