INTRODUCTION
Your LONGVIE heater is especially designed to provide maximum comfort to you and your home. Its large solid injected
aluminumfrontgrillassures the optimum use ofthegeneratedheatin the ambient, maintains normaltemperaturesbehind
theheatertoavoidstickingofparticles,whichwould soil the wall. You can feel safe with absolute security guaranteed by:
Its thermocouple security valve, which cuts the supply of gas in the event of the heater extinguishing due to strong air
currents, momentary interruption of the supply of gas.
Its gas pressure regulator assures an optimum operational; function, avoiding peak pressures in the gas supply
affectingnormal combustion.
Its gas tight combustion chamber, totally enameled, avoids gases which are caused by combustion, to contaminate
the air and ensures a useful , long lasting working life.

CAUTION
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
greaterdiametertoallowfullgasvolumetoheater.Excessivepressurelosswill
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).
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).

• 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
hand, don't try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or

STOP! Read the safety information above on this page.
Press the knob lightly and turn clockwise to the “OFF” position.
Wait five (5) minutes to clear out any gas. If you then smell gas, STOP! Follow
“B” in the safety information above on this page. If you don’t smell gas, go to the
nextstep.
Find the pilot by looking through the viewing window on the front of the unit.
Press the knob down lightly and turn counterclockwise to the “Pilot”.
Press again downwards.
Press the Piezo Ignition button to light the pilot. Repeat this operation with the
knob pressed down until the pilot has lit. When the pilot lights, continue holding

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

LIGHTING INSTRUCTIONS
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
normaldelayofgas from the gas supplythroughthegascontrol on the heater. In thiscase,maintainpressureon the knob
at the “Pilot” position for 30-40 seconds and then try the piezo lighter.
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.
TURN OFF GAS TO APPLIANCE

USSC 11
MAINTENANCE INSTRUCTIONS
As with all fuel burning appliances, it is important to conduct periodic maintenance functions that will allow for contin-
ued 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: Removethe front cover by removing the control knob and the two(2)screws onthe topof the front. Thenslide
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: Lookinsidetheopeningsof the rear of theunitandcheckforforeign materials. Remove any objectswhichmay
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
frontglass.Ifyou find any of these,followthedirectionsbelow to reach the componentstoclean,otherwisecontinue to the
nextstep.
To Remove Pilot: Findthepilot. Loosentheheadof thermocouple, disconnect the pilot gassupplyline,(onlyonthe side
ofthepilot,noton the valve side). Remove the two(2)M4screwsthatholdthepilot in place. Clean with a vacuumcleaner
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
compressedair. Note: Youcanremovethemainburner-pilotassemblyif you don’t unscrew the M4 screws that hold the
pilot to the burner.
Beforereinstallingtheassembly, check the ceramicfibersealinggasket. Ifitis damaged or worn,replacewithnewgasket
availablefromyourdealer.
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
indicatea leak is present and must be repaired. Turn off the gas when making suchrepairs. Check to makesure that the
piezo ignitor still lights the pilot.
STEP 8: While the main burner is ON, Check the flames to verify that they are burning a clean blue color. (See Diagrams 10-
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.
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.
Any safety screen or guard removed for servicing an appliance must be replaced prior to
operating the appliance
