CLASSIC OUTDOOR FURNACE • OWNER'S MANUAL
The chimney connector and chimney should be inspected at least twice
monthly during the heating season to determine if a creosote buildup
has occurred, and to check for corrosion or condensation. If creosote has
accumulated it should be removed to reduce the risk of a chimney fire.
The chimney and chimney connector must be clean and in good condition.

MAINTENANCE SECTIONS

Refer to the Preventive Maintenance Schedule for the recommended intervals
with which to perform these maintenance items.
Section 1 - Water Level
Open the sight gauge valve. The sight gauge tube will fill to indicate the level
of water in the outdoor furnace. Be sure to close the sight gauge valve after
checking water level. The sight gauge valve and tube will drain when the valve
is closed.
Section 2 - Vent Cap
Check that the vent cap fits loosely on the vent opening. Check the vent cap
copper tube for obstruction; clean with a pipe cleaner if needed.
The outdoor furnace vent cap must fit loosely on the vent opening. Do not force the cap
down or try to seal it tightly onto the vent pipe. Do not extend or restrict the vent pipe
or opening. DO NOT ALLOW THE OUTDOOR FURNACE TO BE PRESSURIZED.
Section 3 - Stir Ash
Stir the ashes in the firebox and pull them forward to prevent the ashes
from sealing in moisture on the bottom and along the edges. It is especially
important to scrape the walls and the four corners at the ash line and below.
If this maintenance operation is not performed as directed, deterioration can
result from the moisture trapped between the ashes and the steel.
1. Remove any heavy or solidified ashes. When ashes build up to either the
door frame in the front or the top of the beveled ash pan of the firebox,
they should be removed. A hoe, ash rake and shovel for this procedure
may be purchased from your Central Boiler dealer. Leave enough ashes
and coals to relight the fire.
