preference.
A. Select Appliance Location
When selecting a location for your appliance it is important to
consider the required clearances to walls (See Figure 3.1).
WARNING
Fire Risk
Provide adequate clearance:
• Around air openings.
• For service access.
Locate appliance away from traffi c areas.

B. Construct the Appliance Chase
A chase is a vertical boxlike structure built to enclose the gas
appliance and/or its vent system. Vertical vents that run on
the outside of a building may be, but are not required to be,
installed inside a chase.
Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST
be checked.
Chases should be constructed in the manner of all outside
walls of the home to prevent cold air drafting problems. The
chase should not break the outside building envelope in any
manner.
Walls, ceiling, base plate and cantilever fl oor of the chase
should be insulated. Vapor and air infi ltration barriers should
be installed in the chase as per regional codes for the rest of
the home. Additionally, in reagions where cold air infi ltration
may be an issure, the inside surfaces be sheetrocked and
taped for maximum air tightness.
To further prevent drafts, the ceiling fi restops should be
caulked with high temperature caulk to seal gaps. Gas line
holes and other openings should be caulked with high temperature caulk or stuffed with unfaced insulation. If the appliance is being installed on a cement slab, a layer of plywood
may be placed underneath to prevent conducting cold up
into the room.
WARNING
Fire Risk
• Construct chase to all clearance
specifi cations in manual.
• Locate and install appliance to all
clearance specifi cations in manual.
WARNING
Fire Risk
Odor Risk
• Install appliance on hard metal or wood
surfaces extending full width and depth
