HIGH ALTITUDE
Heaters may be fired at full input up to 2000 ft. (610m) above sea
level. Above 2000 ft. (610m) a high altitude conversion kit may be
required to ensure proper burner performance, please consult the
manufacturer. Be prepared to answer factory questions regarding:
type of fuel for the proposed appliance conversion, gas pressure
available at site, and specific altitude at site. The conversion shall
be carried out by a manufacturer's authorized representative, in
accordance with the requirements of the manufacturer, provincial,
or territorial authorities having jurisdiction and in accordance with
the requirements of the CSA B149.1 or CSA149.2 installation codes.
Maintenance
For best performance, the following maintenance procedures should
be performed before each heating season:
1. Be sure gas and electrical supply to heater are off before
performing any service or maintenance.
2. Check condition of blower scroll and motor. Dirt and dust
may be blown out with compressed air, or a vacuum cleaner
may be used.
3. Check condition of burner. Carefully remove any dust or
debris from inside the burner box or burner cup.
4. Inspect the igniter. Replace igniter if there is excessive carbon
residue, erosion, breakage or other defects.
5. Check the inside of the firing tube with a flashlight. If carbon
or scale are present, scrape out the deposits with a wire
brush or rod, or metal plate attached to a wooden pole.
6. Check to see that the burner observation window is clean
and free of cracks or holes. Clean or replace as necessary.
7. Check the flue pipe for soot or dirt. After cleaning as
necessary, re-attach the flue pipe to the heater.
8. Outside surfaces of heater may be cleaned by wiping with a
damp cloth.
9. A qualified service agency should be contacted for service
other than routine maintenance.
10. Check vent terminal and fresh air inlet to see that they have
not been blocked during the non-heating season. If either
pipe is restricted, the air switch won't close, resulting in a
no-heat situation.
