d. Re-connect gas valve, air-gas mixer and replace bracket. (IMPORTANT: CHECK FOR GAS
LEAKS)
e. Re-set thermostats (IMPORTANT: MAKE SURE EXHAUST VENT IS NO LONGER BLOCKED!)
f. Turn the Munchkin back on** and observe condensate flow.
g. Re-connect the condensate hose to the outside connection.
IT IS EXTREMELY IMPORTANT THAT YOU CHECK FOR LEAKS WHEN
RECONNECTING THE GAS VALVE AND MAKING SURE THE EXHAUST VENT IS NO
LONGER BLOCKED. FAILURE TO DO SO MAY RESULT IN SEVERE PERSONAL INJURY
OR DEATH.
**NOTE: When firing up the boiler for the first few times you may experience some flut-
tering of the gas burner that may result in a flame lockout. This is normal and will
require you to re-cycle the unit until this clears up. This is caused by water still present
in the combustion chamber.
