f) After it has been determined that each appliance remaining connected to the common venting
system properly vents when tested as outlined above, return doors, windows, exhaust fans,
fireplace dampers and any other gas-burning appliance to their previous condition of use.
g) Any improper operation of the common venting system must be corrected so that the installation
conforms to the National Fuel Gas Code, ANSI Z223.1 or CAN/CGA B149, Installation Codes.
When resizing any portion of the common venting system, the common venting system should be
resized to approach the minimum size as determined using the appropriate tables in Part 11 of
the latest or current as amended National Fuel Gas Code, ANSI Z223, 1 or CAN/CGA B149,
Installation Codes.
Heat exchanger surfaces and vent piping should be checked every six months for deterioration and
carbon deposits. Remove all soot or other obstructions from the chimney and flue, which might impede
draft action. Replace any damaged or deteriorated parts of the venting system.
A qualified service technician should follow this procedure when inspecting and cleaning the heat
exchanger and vent pipe.
1. Turn off electrical power and close main manual gas shut-off and allow boiler to cool down
2. Remove the vent pipe running to chimney. Remove top outer panel and flue collector access
panel. Check heat exchanger, vent and chimney for obstruction and clean as necessary.
3. Remove burner from boiler and vacuum the heat exchanger. If heat exchanger is excessively
dirty it may be necessary to remove it from the boiler and wash it down with proper detergent
cleaner. Be aware that the combustion chamber base is insulated with ¼" thick ceramic paper. If
this material is damaged or displaced it must be replaced before starting up the boiler.
4. Reinstall parts removed in steps 2 and 3. Be sure that vent pipe has proper pitch and is properly
sealed. Repair or replace any gaskets, which may have been damaged in steps 2 and 3.
5. CAUTION: When replacing the burner be careful to fully engage the back of the burner box into
the retaining slot in the combustion chamber base. Failure to properly locate the burner will result
in erratic flame operation with the possibility of delayed ignition on light off.
6. Restore electrical power and gas supply to boiler.
7. Place boiler in operation using lighting instructions provided.
8. While the boiler is operating, check for flue gas leaks and proper vent operation. Seal any flue
gas leaks using appropriate gasket or sealing material. Carefully examine the flue collector
access panel and heat exchanger ends.
The MicoFlame is a category 1, 85% efficient when supplied as a non-condensing appliance. When
supplied with the optional condensing cartridge, the MicoFlame is 95% efficient and is considered to be a
category II or IV appliance. Three venting options are available for this boiler. See Figure 2 for details.
