(Do not in any way enlarge or distort it).

 

Not enough heat

1.

Appliance undersized.

1.

This is especially true when a dwelling or room is

 

 

 

 

 

enlarged. Have the heat loss calculated and compare

 

 

 

 

 

to the appliance output (approx. 70% of input).

 

 

 

 

 

Your gas company or installer can supply you with

 

 

 

 

 

this information. If appliance is undersized, replace
