H3.60
ONLY USE A BYPASS PLENUM ARRANGEMENT WHEN CONNECTING AIR CONDITIONING TO A
CHMF/HMF 150/200 FURNACE SYSTEM. OTHER ARRANGEMENTS MAY CAUSE REDUCED AIR
FLOW IN DUCTWORK WHICH MAY CAUSE FURNACE AND AIR CONDITIONING EQUIPMENT TO
OPERATE OUTSIDE THEIR SAFE OPERATING PARAMETERS. FURNACE AND DUCTING SYSTEMS
COULD DEVELOP EXCESSIVE SURFACE TEMPERATURES INCREASING THE RISK OF FIRE,
RESULTING IN EQUIPMENT DAMAGE, PROPERTY DAMAGE, AND PERSONAL INJURY INCLUDING
DEATH.
ALL SEASONAL DUCTING DAMPERS MUST BE CORRECTLY ORIENTED FOR THE APPROPRIATE
MODE OF OPERATION (FURNACE OR AIR CONDITIONING). FAILURE TO CORRECTLY POSITION
THE SEASONAL DUCTING DAMPERS WILL CAUSE FURNACE AND AIR CONDITIONING
EQUIPMENT TO OPERATE OUTSIDE THEIR SAFE OPERATING PARAMETERS. FURNACE AND
DUCTING SYSTEMS COULD DEVELOP EXCESSIVE SURFACE TEMPERATURES INCREASING
THE RISK OF FIRE, RESULTING IN EQUIPMENT DAMAGE, PROPERTY DAMAGE, AND PERSONAL
INJURY INCLUDING DEATH.
H3.65A
DO NOT USE “FAN SUMMER SWITCH (ON MODE)”, “OVERIDE SWITCHES (MANUAL POSITION)”,
“CONTINUOUS FAN OPERATION ON BACK UP FURNACE (IN “ADD ON” CONFIGURATION)”, WHEN
OPERATING THE WOOD FURNACE.
DO NOT CONNECT HRV’S SO THEY ARE CONTROLLING THE CYCLING OF THE FURNACE
CIRCULATION BLOWER.
FAILURE TO COMPLY WITH THIS WILL RESULT IN EXCESSIVE COOLING OF THE EXHAUST
PRODUCTS AS THEY PASS THROUGH THE EXCHANGER PIPES, THE FURNACE FLUE AND
THE CHIMNEY SYSTEM. THIS COOLING WILL RESULT IN THE CONDENSATION OF EXHAUST
PRODUCTS IN THE EXCHANGER AND CHIMNEY RESULTING IN EXCESSIVE CREOSOTE BUILD UP.
THE CREOSOTE BUILD UP WILL RESULT IN REDUCED EFFICIENCIES OF THE EXCHANGER TUBES
AND MAY CAUSE A CHIMNEY FIRE.
