1.3 DETECTION 

SYSTEMS 

It is recommended that carbon monoxide detectors be 
installed wherever oil or gas fired heaters are used. 
Carbon monoxide can cause bodily harm or death. For 
this reason, agency approved carbon monoxide detectors 
should be installed in your residence and properly 
maintained to warn of dangerously high carbon monoxide 
levels. 

There are several sources of possible smoke and flames 
in a residence. Smoke and flames can cause bodily harm 
or death. For this reason, agency approved smoke 
detectors should be installed in your residence and 
properly maintained, to warn early on, of a potentially 
dangerous fire. Also, the house should be equipped with 
approved and properly maintained fire extinguishers. 

Your unit is equipped with safety devices that can prevent it 
from functioning when anomalies are detected such as a 
blocked venting system.  

1.4 

DANGER OF FREEZING 

CAUTION 

If your furnace is shut down during the cold weather 
season, water pipes may freeze, burst and cause serious 
water damage. Turn off the water supply and bleed the 
pipes.

If the heater is left unattended during the cold weather 
season, take the following precautions: 

Close the main water valve in the house and purge the 
pipes if possible. Open all the faucets in the house; 

a. 

b. 

Ask someone to frequently check the house during the 
cold weather season to make sure that there is 
sufficient heat to prevent the pipes from freezing. Tell 
this person to call an emergency number if required.
