Safety Rules
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.
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 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.
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,
ANSI/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 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.
To ensure safe and efficient operation of your unit, you should do
the following:
1. 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.
2. 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.
Frozen Water 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.
CAUTION
!
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 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. 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.
-- o r --
3. Install a reliable remote sensing device that will notify some-
body of freezing conditions within the home.
Winter Shutdown
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 Fig. 10
through Fig. 17)
1. Disconnect the
5
/
8
″ OD rubber hose from the vent drain fit-
ting that is located downstream of the combustion blower.
Insert a funnel into the hose and pour four(4) ounces of san-
itary type (RV) antifreeze into the condensate trap. Recon-
nect the
5
/
8
″ OD rubber hose to the stub on the vent drain
fitting. Secure with the hose clamp.
2. Disconnect the
3
/
4
″ 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
″ 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.
