INSTALLATION

DECIDING

WHERE TO LOCATE YOUR STOVE

1. The stove should be located out of traffic and away from furniture and draperies.

2. This stove should have sufficient access for its safe operation and maintenance.

3. Locate a position where the flue system of the stove can be properly installed without damaging the

integrity of the building. e.g. cutting wall or ceiling joists.

4. When the appliance is installed directly on carpeting, tile or other combustible material other than

wood flooring, the appliance shall be installed on a metal or wood panel extending the full width and
depth of the appliance.

5. Check stove and flue system clearance requirements.

6. Locate the stove where it can be accessed by a gas supply line.

7. Locate the stove in a large and open room that is centrally located in the house. This will optimize

heat circulation and comfort.

8. This stove can be installed in bedrooms.

9. The flow of combustion and ventilation air must not be obstructed.

MINIMUM

CLEARANCES TO COMBUSTIBLES

A – From side wall to stove: 6"
B – From rear wall to stove: 6"
C – Corner clearance: 6"
From top of stove to combustible: 36"
From front of stove to combustible: 60"

FLOOR

PROTECTION

The stove must be installed on rigid flooring. When the stove is installed on any combustible surface other
than wood flooring, a metal or wood panel extending the full width and depth of the unit must be used as a
hearth. There are no other hearth requirements.

WARNING:

- Always maintain required clearances to nearby combustibles to prevent fire hazard. Do not

fill air spaces with insulation. All venting components must maintain a 1" (25mm) clearance
to combustible materials.

- The appliance and vent system must be vented directly to the outside of the building and

never be attached to a chimney serving a separate solid fuel or gas-burning appliance. Each
direct vent appliance must use its own separate vent system. Common vents are prohibited.

- Refer to the manufacturer's instructions included with the venting system for complete

installation procedures.

LOCATION OF THE VENT TERMINAL

The vent terminal must be located observing the minimum clearances shown on pages 6 and 7.
