Operating Instructions
PiLot Light:
1. Turn off the gas to the replace. If not recently done, remove the
glass and let the unit air out for at least ve (5) minutes to
clear out any gas. Turn on gas to the heater. Leak test all joints with
soapy water. NEVER USE OPEN FLAME FOR LEAK TESTING.
Thermopile
2. Start the pilot by pressing the gas control knob and turning it to PILOT.
While holding the gas control knob in, press the piezo ignitor several
times until the pilot light starts. Hold the gas control knob in for 30
seconds. Check that the pilot has fully engulfed the thermocouple
assembly (see Figure 4).
3. Start the main burner by turning the gas control knob to ON and then
Figure 4. Pilot Flame
turn the rocker switch to ON. Check that all burner ports have ame.
4. Leak test all gas joints again.
VentuRi aDjustment:
The venturi adjustment lever is located on the right side of the unit, behind the surround panel (see
Figure 5). To avoid touching hot surfaces under the unit, use the Door Tool to adjust the venturi.
The venturi allows the amount of air coming into the replace to be adjusted in order to accommodate
different climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot
ame is burning normally and none of the burner ports are plugged. Let the replace burn for roughly
fteen (15) minutes and then examine the ames. The
ideal ame will be blue at the base and light orange
above. The ames should be of medium height. If the
ames look like this, no venturi adjustment is needed. If
the ames are fairly short and mostly blue, the replace
is getting too much air. Therefore, the air shutter should
be closed (push in) slightly until the correct ames are
achieved. Flames that are very orange, with tall dark
stringy tips are not getting enough air. Open (pull out)
the venturi until the ames clean up. If the venturi is
opened, then closed all the way, and the correct ames

cannot be attained, turn off the gas and contact the
dealer.
Warning: Incorrect venturi adjustment may lead to improper combustion, which is a safety hazard.
Contact the dealer if there is any concern about the venturi adjustment.

Maintenance And Service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specically approved with this appliance, may result in property damage or personal injury.
At least once a year, run through the following procedures to ensure the system is clean and working
properly. Check the burner to see if all the ports are clear and clean. Check the pilot to make sure it is not
blocked by anything. The pilot ame should be blue with little or no yellow on the tips.
The venting system must be periodically examined; it is recommended the examination is done by a
qualied person.
cLeaning the gLass:
When the replace is cool, remove the glass door. See maIntenance anD serVIce - glass Door remoVal.
Check the gasket material on the back of the glass, making sure that it is attached and intact.
During a cold start up, condensation will form on the glass. This is a normal condition with all replaces.
However, this condensation can allow dust and lint to cling to the glass surface. Initial paint curing of the
appliance can leave a slight lm on the glass. The glass will need cleaning after the replace has cooled
off from the rst burn and about two weeks after rst burn. Use a mild glass cleaner and a soft
cloth. Abrasive cleaners will damage the glass and painted surfaces. Depending on the amount
of use, the glass should require cleaning no more than two or three times a season. Do not clean the
glass when it is hot.
cLeaning the fiRebox:
Remove the glass material. Vacuum the bottom of the rebox thoroughly. At this time, inspect the burner
tube for cracking or severe warping. If a problem is suspected, contact the dealer.
RePLacing the gLass:
The glass in the replace is a high temperature ceramic. If the glass is damaged in any way, a factory
replacement is required (see parts lIst). Wear gloves when handling damaged glass door assembly
to prevent personal injury. Do not operate with the glass front removed, cracked or broken. Removal
and replacement of the glass from the door must be done by a licensed or qualied service person.
The glass must be purchased from an ENVIRO dealer. No substitute materials are allowed.
Remove the door (see page 11). The replacement glass will come with a new gasket installed. Remove
any silicone remnants from the door. Apply high temperature silicone to the two vertical faces of the
door and install the new piece of glass with gasket (be sure to maintain edge clearances). Apply even
pressure to the glass to allow the silicone to adhere to the gasket material.
check PiLot anD buRneR fLames:
Periodically do a visual check of the pilot ames. One ame should encompass the ignitor and thermocouple
and the other should burn over the burner ports (see Figure 7). Also check that the burner is operating
correctly, refer to Venturi Adjustment section.
