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, below the door (see Figure 5).
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.
Thermocouple
The ideal ame will be blue at the base and light orange
above (see Figure 64). 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.
Figure 5: Adjusting the venturi air setting.
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 agency.
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 sometimes 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 behind the glass, a temporary problem. 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 logs carefully, as they are very fragile. Gently remove all the embers and rock wool and place
on a paper towel. Vacuum the bottom of the rebox thoroughly. Carefully clean any dust off the logs and
remove any lint from the burner and pilot. At this time, inspect the burner pan for cracking or severe
warping. If a problem is suspected, contact the dealer. Check the logs for deterioration or large amounts
of soot; a small amount on the bottom side of the logs is normal. Replace the logs and embers as in the
seconDary InstallatIon - log set anD ember InstallatIon section. If new/more embers and rock wool are
required, contact your nearest ENVIRO 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. When the glass door assembly is being transported, it must be wrapped in
newsprint and tape and/or a strong plastic bag. 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.
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 Figure
64.
