MF Series
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
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
using small pieces of wood keeping only enough wood 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 smouldering 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.
Customer is 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.
The Ranco Temperature control is giving the user an error message.
Instructions for dealing with Ranco ETC settings and error codes are included in the owner's manual
on page 16.
