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, Hearth & Home Technologies recommends that 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 temp
caulk or stuffed with unfaced insulation. If the appliance is
being installed on a cement slab, we recommend that a layer
of plywood be placed underneath to prevent conducting cold
up into the room.
WARNING

WARNING
Fire Risk
Explosion Risk
Asphyxiation Risk
Do NOT connect this gas appliance to a
chimney fl ue serving a separate solid-fuel
or gas burning appliance.
• Vent this appliance directly outside.
• Use separate vent system for this
appliance.
May impair safe operation of this appliance or
other appliances connected to the fl ue.
B. Use of Elbows
CAUTION
ALL vent configuration specifications MUST be
followed.
• This product is tested and listed to these
specifi cations.
• Appliance performance will suffer if specifi cations
are not followed.
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 5.1).
Two 45° elbows may be used in place of one 90° elbow. On
45° runs, 1 ft of diagonal is equal to 8-1/2 in. horizontal run
and 8-1/2 in. vertical run. A length of straight pipe is allowed
between two 45° elbows (see Figure 5.1).
Horizontal
Figure 5.1 Using Two 45° Elbows
C. Measuring Standards
Vertical and horizontal measurements listed in the vent diagrams were made using the following standards.
• Pipe measurements are shown using the effective length
of pipe (see Figure 5.2).
• Measurements are made from the appliance outer wrap,
not from the standoffs.
• Horizontal terminations are measured to the outside
mounting surface (flange of termination cap) (see
Figure 4.1).
• Vertical terminations are measured to top of last pipe
before termination cap.
• Horizontal pipe installed level with no rise.

WARNING
Fire Risk
Explosion Risk
Do NOT pack insulation or other combustibles between fi restops.
• ALWAYS maintain specifi ed clearances around venting and fi restop systems.
• Install fi restops as specifi ed.
Failure to keep insulation or other material away from vent pipe may cause fi re.
The fi rst 90° elbow MUST be a starter elbow.
To replace the fi rst starter elbow with two 45° elbows, refer to Figure 5.4. All other 90° elbows can be replaced with two 45°
elbows.
General Rules:
• SUBTRACT 3 ft (914 mm) from the total H measurement for each 90° elbow installed horizontally.
SUBTRACT 1-1/2 ft (457 mm) from the total H measurement for each 45° elbow installed horizontally.
• A maximum of three 90° elbows (or six 45° elbows) may be used in any vent confi guration. Some elbows may be installed
horizontally. See Figure 5.6.
• Elbows may be placed back to back anywhere in the system as long as the fi rst 90° elbow is a starter elbow except as
shown in Figure 5.4.
• When penetrating a combustible wall, a wall shield fi restop must be installed.
• When penetrating a combustible ceiling, a ceiling fi restop must be installed.
