7.
Check all gas connections and gas controls (electrical valves, manual shut-off valves, regulators, etc.) for leaks.
8.
This inspection should include a complete operational check of the unit including all electrical and mechanical components.
NOTE
: If cabinet front was removed in order to inspect the unit and controls, it must be reinstalled prior to operating the unit.
You as the owner/user should inspect the unit periodically during the heating season. Particular attention should be given to
the following:
A.
Periodically observe the main burner flame to assure it is burning with a hard blue flame with well-defined burner ports. (See Figure
16.) If flame appears yellow or burner has a lazy flame, shut furnace down and contact a qualified service person.
B.
Periodically inspect the vent for obstructions or presence of soot. Soot is formed whenever combustion is incomplete. This is your
visual warning that the furnace is operating in an unsafe manner. If soot is present, immediately shut furnace down and contact
your dealer or a qualified service person.
C.
Circulating air through the front grille must not be blocked. Keep filter clean to assure adequate air flow.
The removable, washable type filter should be cleaned or replaced several times during the year. This will depend upon the usage and
location of the unit. Dirty filters restrict air flow across the heat exchanger and coils. This results in inadequate cooling and shortens the
life expectancy of the heat exchanger, motors and compressor.
