4. Check that the temperature settings are correct.
The furnace should be set on Heating Mode (H1)
and the high temperature setting should be set no
higher than 185° F.
5. Check chimney draft. If the chimney has been
extended too far or has a strong wind blowing over
it, it may cause a draft down the furnace.
6. Check water level.
7. Make sure the door and ash drawer are air tight.
8. Check to ensure all pumps in the system are
running.
If the furnace has shut down:
1. Check to ensure that the unit has power (does the
light work?).
2. Check to ensure the Furnace On/Off switch is in the
On position.
3. Check the water temperature (furnace has a high
temperature cut out of 190 degrees F. and turns on
again at 140 degrees).
If there is a chimney fire:
1. Make sure the firebox and ash pan doors are
tightly closed.
2. Close all combustion air inlets on the furnace.
If there is a power failure:
1. Open all flow-check and zone valves in the system.
Depending on the system design, this may allow
convective circulation.
NOTE: This does not apply to
gravity systems, as they have no flow-check valves
and will continue to operate normally without
electricity.
2. It is important to remember that the heating
systems cannot dispose of a great deal of heat
without the circulator(s) running. Avoid over-firing!
DO NOT LOAD LARGE AMOUNTS OF SOLID FUEL
INTO THE FURNACE!
Fire the furnace cautiously
until you are able to determine how quickly the
heat system is able to absorb the heat being
produced by the furnace.
3. When the power has returned, reset all flow-check
and zone valves and resume normal operation of
the system.
If there is smoke leaking out of the door.
Small
amounts of smoke leakage is normal due to the fan
pressure and restricted exhaust.
1. Check to ensure door is sealing properly.
2. If the seal is worn out it will have to be replaced.
3. The door may need to be adjusted. To do this
loosen the Door Latch Bearings and Door Hinge
bearings and set the door so it seals tightly against
the door jamb.
If the furnace has an excessive amount of creosote
either in the firebox or in the bypass
1. Check to ensure the furnace is sized accurately
according to heat demand. If the furnace is
oversized it will idle and cause this. If the weather
is warm or mild burn a small hot fire keeping
only enough fuel to last until your next burn time
(generally 12 hour burn time is best). It will allow
the furnace to burn more often with greater
efficiency and have less fuel smoldering during
idle, creating less creosote.
2. If the chimney and/or bypass become plugged
with creosote it will be necessary to scrape the
creosote out to obtain a proper burn in the firebox.
Having to fill the furnace with water more then once
a week or more then a few gallons of water per
week and there is no obvious explanation
1. Check the temperature settings and gasket on
the door and ash drawer to ensure the furnace
is not over temperature and steaming. If water
temperature reaches levels over 200 degrees
Fahrenheit the water will steam and water loss will
occur.
2. Check the perimeter of the furnace for water
puddles collecting or dripping from the furnace.
If water is found open the rear door panel and
search the floor to find the source of the water.
3. Check all plumbing in the system to ensure there
are no leaks.
