MANUFACTURERS GENERAL VENTING
GUIDELINES
This information is compiled by the manufacturer as a very general rule for
single appliance venting of the EG 28 gas stove with 4" Type B gas vent.
Venting code and regulations may vary from area to area, please check with
the local, state/provincial codes regarding the suitability of your application.
For other special venting requirements, please refer to the local, state/provincial or national codes.
For best venting performance, we recommend total vent height of 10
ft (3m) to 30 ft (9m). Total horizontal length depends on the number
of elbows used. The venting
Should never slope down. 1/4" rise per 2' horizontal is
recommended.
If practical, it is best to locate the appliance to permit the use of
shorter horizontals and fewer elbows.
-Two 90° elbows, maximum total horizontal length of 20 ft (6m).
-Three 90° elbows, maximum total horizontal length of 13 ft (3.8m).
-Four 90° elbows, maximum total horizontal length of 6 ft (1.9m).
-Five 90° elbows, maximum total horizontal length of 0 ft (0m).
If 45° elbows are used, one 90° elbow is equivalent to two 45°
elbows.
Venting rise should be a minimum of 1 ft (.31m).from the top of the
unit before any horizontal run.
The bottom of the vent cap shall extend at least 2 ft. (.6m) above the
highest point of the roof where it passes through and at least 2 ft
(.6m) higher than any portion of the roof within a horizontal distance
of 10 ft. (3m).

MAINTENANCE AND TECHNICAL
Annually check to ensure that your
Venting system is clear.
Periodically check the pilot and burner. Check to
see that all the burner ports are clean and clear.
Check the pilot head for blockage. Check to ensure
the pilot flame is blue with small yellow tips.
CLEANING OF GLASS
Do not clean glass when hot
It will be necessary to clean the ceramic glass
periodically. During a cold start up, condensation
will sometimes form on the glass; this is a normal
condition with all gas fireplaces and stoves.
However, this condensation can allow dust and lint
to cling to the glass surface. Initial paint curing of the
appliance can leave behind a slight film on the glass.
This is a temporary problem. It is therefore
recommended that the glass be cleaned initially after
about the first two weeks of use.
After that, depending upon the amount of use,
cleaning should be required no more than two or
three times per season.
To clean the door, use a mild glass cleaner and a
soft cloth. Abrasive cleaners will damage the glass
and gold surfaces.
OPENING THE DOOR
Turn unit off and wait until the appliance has cooled
down.
1. Open the right hand hinged side flap, which will
expose a door fastener. Using a 1/2" wrench,
loosen the fastener.
1. Due to the shape of the bay window door. You
must also open the left-hand side flap before
attempting to open the door.
3. Ensure the door is properly fastened after
cleaning before attempting to re-light the appliance.
TO REPLACE DOOR AND GLASS ASSEMBLY
The glass in this appliance is an integral part of the
door assembly. If the glass is damaged or broken a
replacement door assembly including glass must be
fitted.
To Replace:
• Open door fully
• Lift door vertically so that hinge pins lift out of
hinge receivers.
• Return the door assembly to dealer.
The door and glass assembly must be replaced
as a complete unit. By your ENVIRO Dealer.
No substitute materials are allowed.
Use extreme caution cleaning up broken glass. Use
thick gloves and broom to brush glass up.
FOR CLEANING THE INSIDE OF THE FIREBOX
Remove the logs carefully from the firebox. Gently
remove the embers and place on a piece of paper
towel, until ready to replace.
Vacuum the firebox thoroughly. Carefully clean off
any dust on the logs and remove any lint from the
main burner and pilot burner.
After carefully replacing the log and embers in their
correct positions, and the door has been resealed,
re-light the pilot, following the instructions on the
attached label.
