Hearth & Home Technologies Inc.

LIMITED LIFETIME WARRANTY

Hearth & Home Technologies Inc., on behalf of its hearth brands (”HHT”), extends the following warranty for
HHT gas, wood, pellet, coal and electric hearth appliances that are purchased from an HHT authorized dealer.

WARRANTY COVERAGE:

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
begins on the date of first occupancy of the dwelling or six months after the sale of the product by an independent,
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
parts and labor for covered components is produced in the following table.

The term “Limited Lifetime” in the table below is defined as: 20 years from the beginning date of warranty coverage for
gas appliances, and 10 years from the beginning date of warranty coverage for wood, pellet, and coal appliances. These

I. Control Module Operation

1. The control module has an ON/OFF/REMOTE selector
switch that must be set. See Figure 2.3.

OFF Position: Appliance will ignore all power inputs and

will not respond to any commands from a wall switch or
remote. The unit should be in the OFF position during
installation, service, battery installation, fuel conversion,
and in the event that the control goes into LOCK-OUT
mode as a result of an error code.

ON Position: Appliance will ignite and run continuously

in the HI fl ame setting, with no adjustment in fl ame
output. This mode of operation is primarily used for
initial installation or power outage operation with battery
backup.

REMOTE Position: Appliance will initiate commands

from an optional wired wall switch and/or the wireless
remote (RC300).

2. If using a wired wall switch with the module in REMOTE
mode, the fl ame output can be adjusted with the HI/LO
selector switch on the module. See Figure 2.3. Note
that the fl ame HI/LO selector switch will become inactive
once an optional remote control (RC200/RC300) is
programmed to the control module. Note that the control
module will always ignite the fi replace on HI and remain
so for the initial 10 seconds of operation. If the HI/LO
is switched to the LO position, the fl ame output will
automatically drop to the lowest setting after the fl ame
has been established for 10 sec. After this 10 second
period, the fl ame can be adjusted from HI to LO with
the switch.

3. The control module has safety feature that automatically
shuts down the fi replace after 9 hours of continuous
operation without receiving a command from the RC300
remote.

4. If you intend to use both an optional wired wall switch
and the RC300 remote control to operate your fi replace,
the wall switch will override any commands given by
the remote.

M. Frequently Asked Questions

ISSUE SOLUTIONS

Condensation on the glass

Blue fl ames

Odor from appliance

Film on the glass

Metallic noise

Is it normal to see the pilot fl ame burn
continually?

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

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

When fi rst operated, this appliance may release an odor for the fi rst several hours. This is caused
by the curing of the paint and the burning off of any oils remaining from manufacturing. Odor may
also be released from fi nishing materials and adhesives used around the appliance.

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 to remove deposits left by oils from the manufacturing
process. 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 appliance.

In an intermittent pilot ignition system (IPI), the pilot fl ame should turn off when appliance is

B. Design and Installation Considerations

Heatilator 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 requirements.

• 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

1/2 - 3/4 in. length, #6 or #8 Self-drilling screws
Caulking material (300ºF minimum 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

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

COMBUSTIBLE FLOORING MAY BE INSTALLED
