HHT warrants to the original owner of the HHT appliance at the site of installation, and to any transferee taking ownership
of the appliance at the site of installation within two years following the date of original purchase, that the HHT appliance
will be free from defects in materials and workmanship at the time of manufacture. After installation, if covered compo­nents manufactured by HHT are found to be defective in materials or workmanship during the applicable warranty period,
HHT will, at its option, repair or replace the covered components. HHT, at its own discretion, may fully discharge all of its
obligations under such warranties by replacing the product itself or refunding the verified purchase price of the product
itself. The maximum amount recoverable under this warranty is limited to the purchase price of the product. This warranty
is subject to conditions, exclusions and limitations as described below.

WARRANTY PERIOD:

Warranty coverage begins on the date of original purchase. In the case of new home construction, warranty coverage

authorized HHT dealer/ distributor, whichever occurs earlier. The warranty shall commence no later than 24 months
following the date of product shipment from HHT, regardless of the installation or occupancy date. The warranty period for

K. Frequently Asked Questions

ISSUE SOLUTIONS

Condensation on the glass

Blue fl ames

Odor from fi replace

Film on the glass

Metallic noise

This is a result of gas combustion and temperature variations. As the fi replace warms, this
condensation will disappear.

This is a result of normal operation and the fl ames will begin to yellow as the fi replace is al-
lowed to burn for 20 to 40 minutes.

When fi rst operated, this fi replace may release an odor for the fi rst several hours. This is
caused by the curing of materials from manufacturing. Odor may also be released from
fi nishing materials and adhesives used near the fi replace. These circumstances may require
additional curing related to the installation environment.

This is a normal result of the curing process of the paint and logs. Glass should be cleaned
within 3 to 4 hours of initial burning. A non-abrasive cleaner such as gas fi replace glass
cleaner may be necessary. See your dealer.

Noise is caused by metal expanding and contracting as it heats up and cools down, similar to
the sound produced by a furnace or heating duct. This noise does not affect the operation or
longevity of the fi replace.

B. 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, fi re offi 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 confi guration to be used.

• Gas supply piping.

• Electrical wiring requirements.

• Framing and fi nishing details.

• Whether optional accessories—devices such as a fan,
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 qualifi ed
service technician, service agency or your dealer.

C. Tools and Supplies Needed

Before beginning the installation be sure that the following
tools and building supplies are available.

Tape measure Framing material
Pliers Non-corrosive leak check solution
Hammer Phillips screwdriver
Gloves Framing square
Voltmeter Electric drill and bits (1/4 in.)
Plumb line Safety glasses
Level Reciprocating saw
Manometer Flat blade screwdriver
1/2 - 3/4 in. length, #6 or #8 Self-drilling screws
Caulk (minimum of 300ºF continuous exposure rating)

One 1/4 in. female connection (for optional fan).

D. Inspect Appliance and Components

• Carefully remove the appliance and components from
the packaging.

• The vent system components and decorative doors and
fronts may be shipped in separate packages.

• If packaged separately, the log set and appliance grate
must be installed.

• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.

• Read all of the instructions before starting the instal-

lation. Follow these instructions carefully during the
installation to ensure maximum safety and benefi t.

WARNING! Risk of Fire or Explosion! Damaged parts
could impair safe operation. DO NOT install damaged, in-
complete or substitute components. Keep appliance dry.

Hearth & Home T echnologies disclaims any responsibility for ,
and the warranty will be voided by, the following actions:

• Installation and use of any damaged appliance or vent

system component.

• Modifi cation of the appliance or vent system.

• Installation other than as instructed by Hearth & Home

Technologies.

• Improper positioning of the gas logs or the glass door.

• Installation and/or use of any component part not approved

by Hearth & Home Technologies.

Any such action may cause a fi re hazard.

Framing and Clearances

A. Selecting Appliance Location

When selecting a location for the appliance it is important to
consider the required clearances to walls (see Figure 5.1).

WARNING! Risk of Fire or Burns! Provide adequate
clearance around air openings and for service access.

Due to high temperatures, the appliance should be locat­ed out of traffi c and away from furniture and draperies.

B. 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 fi restops and wall shield
fi 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 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 regions where cold
air infi ltration may be an issue, the inside surfaces may be
sheetrocked and taped for maximum air tightness.

To further prevent drafts, the wall shield and ceiling fi re-
stops should be caulked with caulk with a minimum of

300º F continuous exposure rating to seal gaps. Gas line
holes and other openings should be caulked with caulk
with a minimum of 300 ºF co ntinuous exposure rating 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.

C. Clearances

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 specifi 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 fi replace or chimney.

• Failure to maintain airspace may cause overheating and
a fi re.

C. Use of Elbows

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 7.1).

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 7.1).
