Gas equipment and their vent systems must be

inspected annually by a qualiﬁed service agency to

assure safe and reliable operation.

Frozen Plumbing and

Water Damage Hazard

If the residence is unattended in severely cold

weather, burner primary control safety lockout,

heating system component failures, power

outages or other electrical system failures could

result in frozen plumbing and water damage in a

matter of hours. For protection, take preventive

actions such as having a security system installed

that operates during power outages, senses low

temperature and initiates an effective action.

Consult with your heating contractor or a home

security agency.

Burn Hazard, Hot Surface

Burner ﬂange and air tube are hot

when burner is in operation. Do not

service this area during or

immediately after operation. Allow

area to cool.

instructions is not followed exactly, a ﬁre,

explosion, or production of carbon monoxide

may result causing property damage, personal

injury or loss of life. The qualiﬁed service agency
