SafetyRules
Your unit is built to provide many years of safe and dependable
service providing it is properly installed and maintained. However,
abuse and/or improper use can shorten the life of the unit and
create hazards for you, the owner.
A. The U.S. Consumer Product Safety Commission encourages
installation of carbon monoxide alarms. There can be various
sources of carbon monoxide in a building or dwelling. The
sources could be gas-fired clothes dryers, gas cooking
stoves, water heaters, furnaces, gas-fired fireplaces, wood
fireplaces.
Carbon monoxide can cause serious bodily injury and/or
death. Carbon monoxide or "CO" is a colorless and odorless
gas produced when fuel is not burned completely or when the
flame does not receive sufficient oxygen.
a.
Therefore, to help alert people of potentially dangerous carbon
monoxide levels, you should have a commercially available
carbon monoxide alarm that is listed by a nationally
recognized testing agency in accordance with Underwriters
Laboratories Inc. Standard for Single and Multiple Station
Carbon Monoxide Alarms, ANSl/UL 2034 or the CSA 6.19-01
Residential Carbon Alarming Devices installed and
maintained in the building or dwelling concurrently with the
gas-fired furnace installation (see Note below). The alarm
should be installed as recommended by the alarm
manufacturer's installation instructions.
There can be numerous sources of fire or smoke in a building
or dwelling. Fire or smoke can cause serious bodily injury,
death, and/or property damage. Therefore, in order to alert
people of potentially dangerous fire or smoke, you should have
fire extinguisher and smoke alarms listed by Underwriters
Laboratories installed and maintained in the building or
dwelling (see Note below).
Note: The manufacturer of your furnace does not test any alarms
and makes no representations regarding any brand or type
of alarms.
C.

2.
To ensure safe and efficient operation of your unit, you should
do the following:
Thoroughly read this manual and labels on the unit. This
will help you understand how your unit operates and the
hazards involved with gas and electricity.
Do not use this unit if any part has been under water.
Immediately call a qualified service technician to inspect the
unit and to replace any part of the control system and any gas
control which has been under water.
3. Never obstruct the vent grilles, or any ducts that provide
air to the unit. Air must be provided for proper combustion
and ventilation of flue gases.
FrozenWater Pipe Hazard
WATER DAMAGE TO PROPERTY HAZARD
Failure to follow this caution may result in property
damage.
Do not leave your home unattended for long periods
during freezing weather without turning off water
supply and draining water pipes or otherwise
protecting against the risk of frozen pipes and
resultant damage.
Your furnace is designed solely to provide a safe and comfortable
living environment. The furnace is NOT designed to ensure that
water pipes will not freeze. It is equipped with several safety
devices that are designed to turn the furnace off and prevent it from
restarting in the event of various potentially unsafe conditions.
If your furnace remains off for an extended time, the pipes in your
home could freeze and burst, resulting in serious water damage.
If the structure will be unattended during cold weather you should
take these precautions.
1. Turn off the water supply to the structure and drain the water
lines if possible and add an antifreeze for potable water to
drain traps and toilet tanks. Open faucets in appropriate
areas.
2.
3.
-or-
Have someone check the structure frequently during cold
weather to make sure it is warm enough to prevent pipes
from freezing. Instruct them on a service agency to call to
provide service, if required.
-or-
Install a reliable remote sensing device that wilt notify
somebody of freezing conditions within the home.
WinterShutdown
If you go away during the winter months and do not leave the heat
on in your home, the plastic transition box and the condensate trap
on the furnace must be protected from freeze damage.(See
Figure 11 trough Figure 20)
1. Disconnect the 5/8"(15.9mm) OD rubber hose from the vent
drain fitting that is located downstream of the combustion
blower. Insert a funnel into the hose and pour four(4) ounces
of sanitary type (RV) antifreeze into the condensate trap.
Reconnect the 5/8"(15.9mm) OD rubber hose to the stub on
the vent drain fitting. Secure with the hose clamp.
2. Disconnect the 3/4" (15.9mm)OD rubber hose from the
condensate trap. Insert a funnel into the hose and and pour
four(4) ounces of sanitary type (RV) antifreeze into the
plastic Transition box. Squeeze the hose together near the
end and quickly reconnect the 3/4" (19.1mm) OD rubber
hose to the stub on the condensate trap. Secure with the
hose clamp.
When you return home, your furnace will be ready to start, as it is
not necessary to drain the antifreeze from the furnace.

2. This furnace is NOT to be used for temporary heat of buildings
or structures under construction.
3.
4.
5.
6.
7.
Install the vent pipes as short as practical. (See Gas Vent
Installation section).
Do NOT install furnace directly on carpeting, tile or other
combustible material other than wood flooring.
Maintain clearance for fire safety and servicing. A front
clearance of 24" (609.6mm) required and 30" (762mm)
recommended for access to the burner, controls and filter.
See clearance requirements in Figure 3.
Use a raised base if the floor is damp or wet at times.
Residential garage installations require:
• Burners and ignition sources installed at least 18"
(457.2mm) above the floor.
8.
9.
Furnace must be located or physically protected from
possible damage by a vehicle.
If the furnace is to be suspended from the floor joists in a
basement or a crawl space or the rafters in an attic, it is
necessary to use steel pipe straps or an angle iron frame to
attach the furnace. These straps should be attached to the
furnace with sheet metal screws and to the rafters or joists
with bolts. The preferred method is to use an angle iron frame
bolted to the rafters or joists.
Local codes may require a drain pan under the entire furnace
and condensate trap when the furnace is installed in attic
application.
This furnace may be used for construction heat provided that all
the following conditions are met:
The furnace is permanently installed with all electrical
wiring, piping, venting and ducting installed according to
these installation instructions. A return air duct is provided,
sealed to the furnace casing, and terminated outside the
space containing the furnace. This prevents a negative
pressure condition as created by the circulating air blower,
causing a flame rollout and/or drawing combustion products
into the structure.
• The furnace is controlled by a thermostat. Itmay not be "hot
wired" to provide heat continuously to the structure without
thermostatic control.
Clean outside air is provided for combustion. This is to
minimize the corrosive effects of adhesives, sealers and
other construction materials. It also prevents the
entrainment of drywall dust into combustion air, which can
cause fouling and plugging of furnace components.
The temperature of the return air to the furnace is
maintained between 55° F (13° C) and 80° F (27° C), with no
evening setback or shutdown. The use of the furnace while
the structure is under construction is deemed to be
intermittent operation per our installation instructions.
The air temperature rise is within the rated rise range on the
furnace rating plate, and the firing rate has been set to the
rating plate value.
The filters used to clean the circulating air during the
construction process must be either changed or thoroughly
cleaned prior to occupancy.
The furnace, ductwork and filters are cleaned as necessary
to remove drywall dust and construction debris from all
HVAC system components after construction is completed.
After construction is complete, verify furnace operating
conditions including ignition, input rate, temperature rise
and venting according to these instructions.
