Getting Started

A. Design and Installation Considerations

Heat & Glo direct vent gas appliances are designed to
operate with all combustion air siphoned from outside of

the building and all exhaust gases expelled to the outside.
No additional outside air source is required.

Installation MUST comply with local, regional, state and

national codes and regulations. Consult insurance carrier,
local building inspector, re ofcials or authorities having
jurisdiction over restrictions, installation inspection and
permits.

Before installing, determine the following:

• Where the appliance is to be installed.

• The vent system conguration to be used.

• Gas supply piping.

• Electrical wiring requirements.

• Framing and nishing details.

• Whether optional accessories—devices such as a wall

switch or remote control—are desired.

Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualied
service technician, service agency or your dealer.

D. Floor Protection

NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly
on carpeting, vinyl, tile or any combustible material other
than wood.

WARNING! Risk of Fire! Maintain specied air space

clearances to appliance and vent pipe:

• Insulation and other materials must be secured to prevent

accidental contact.

• The chase must be properly blocked to prevent blown

insulation or other combustibles from entering and

making contact with replace or chimney.

• Failure to maintain airspace could cause overheating
and re.

Figure 3.12 Floor Protection

C. Constructing the Appliance Chase

A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should be enclosed inside the chase.

NOTICE: Treatment of ceiling restops and wall shield
restops and construction of the chase may vary with the

type of building. These instructions are not substitutes
for the requirements of local building codes. Therefore,
you MUST check local building codes to determine the
requirements to these steps.

Chases should be constructed in the manner of all out­side walls of the home to prevent cold air drafting prob-

lems. The chase should not break the outside building
envelope in any manner.

Walls, ceiling, base plate and cantilever oor of the chase
should be insulated. Vapor and air inltration barriers

should be installed in the chase as per regional codes for

the rest of the home. Additionally, in regions where cold
air inltration may be an issue, the inside surfaces may be
sheetrocked and taped (or an equivalent method may be
used) to achieve maximum air tightness.

To further prevent drafts, the wall shield and ceiling re­stops should be caulked with caulk with a minimum of
300 ºF continuous exposure rating to seal gaps. Gas line
holes and other openings should be caulked with caulk
with a minimum of 300 ºF continuous exposure rating or
stuffed with unfaced insulation. If the appliance is being

installed on a cement surface, a layer of plywood may be
placed underneath to prevent conducting cold up into the

room.

Note: Figure 3.10 and Figure 3.11, and Figure 3.12 show the
replace installed on the oor. However, this replace can be
elevated off the oor provided that the replace is properly

supported by framing materials and the ceiling clearances are

maintained.
