Figure 3.4 Clearances to Combustibles

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.

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 may cause overheating and
a re.

If the appliance is to be placed directly on the oor, the
non-combustible hearth material will be limited to 3/4 in.
thick, including the oor adhesive. If the hearth mate­rial will exceed 3/4 in. thick, the appliance will need to
be shimmed from the oor appropriately to maintain 1/4
in. minimum space between the oor hearth and hearth
refractory.

The base of the replace may sit on a combustible sur­face. The area in front of the replace must be protected
by a noncombustible hearth extension, unless the re-

place is raised a minimum of three inches above the com-

bustible oor or hearth. See Figures 3.5, 3.6 and 3.8.

C. Approved Pipe

This appliance is approved for use with Hearth & Home
Technologies DVP or SLP venting systems. Refer to Sec­tion 12.A for vent component information and dimensions.

DO NOT mix pipe, ttings or joining methods from differ­ent manufacturers.

The pipe is tested to be run inside an enclosed wall.

There is no requirement for inspection openings at each

joint within the wall.

WARNING! Risk of Fire or Asphyxiation. This appli­ance requires a separate vent. DO NOT vent to a pipe
serving a separate solid fuel burning appliance.

D. Use of Elbows

WARNING! Risk of Fire. This appliance requires a mini­mum of 24 inches of vertical venting before attaching any
elbow to the appliance. DO NOT attach elbow directly to
the appliance.

Diagonal runs have both vertical and horizontal vent as­pects when calculating the effects. Use the rise for the
vertical aspect and the run for the horizontal aspect. See
Figure 4.4.

Two 45º elbows may be used in place of one 90º elbow.
On 45º runs, one foot of diagonal is equal to 8-1/2 in. (216
mm) horizontal run and 8-1/2 in. (216 mm) vertical run. A
length of straight pipe is allowed between two 45º elbows.
See Figure 4.4.

Figure 4.5 shows the vertical and horizontal offsets for
DVP elbows.
