(9) Residue may be removed from the firebox or left to be burned during the
next fire. It is good practice to leave a layer of ash approximately one inch
deep in the base of the firebox.
DISPOSAL OF ASHES
Ashes should be placed in a metal container with a tight fitting lid. The closed
container of ashes should be placed on a non-combustible floor or on the ground,
well away from all combustible materials, pending final disposal. If the ashes are
disposed of by burial in soil or otherwise locally dispersed, they should be
retained in the closed container until all cinders have thoroughly cooled.
WARNING – Ashes usually contain live dormant coals, which may burn for many
hours after a recognizable flame has disappeared. Use extreme caution when
handling and disposing ashes.
IMPORTANT – No other waste shall be placed in this container.
1.6 Safety
If the boiler overheats due to improper operation the following precautions should
be taken:
(1) DO NOT shut off power. The circulation pump must be kept running to
disperse excessive heat.
(2) Manually close the damper door by unhooking the chain.
(3) Increase all thermostats in the house to maximum to help disperse
excessive heat.
(4) Excessive heat caused by extreme over-firing or a control malfunction
may cause the relief valve to blow off water/steam into the firebox. Do not
be alarmed. The relief valve will reseat when the excessive pressure has
been released.
(5) Do not add more fuel until you are certain that all controls are functioning
properly and no damage has been done to the boiler.
WARNING – The maximum opening of the combustion air damper is preset at
the factory. DO NOT adjust the stop or attempt to increase the
combustion air by any means.
