6.1
OUTDOOR VENTING
When fitted with the factory supplied rain shield and UL approved vent cap, the MicoFlame is self-venting.
The following applies to outdoor installations:
1. Use only factory supplied rain shields.
2. Periodically check to ensure that air intake and vent cap are not obstructed.
3. Locate boiler at least 3 feet away from any overhang.
4. Locate boiler at least ten feet from building air intake.
5. Avoid installation in areas where runoff from adjacent building can spill onto boiler.
6.2
SIDEWALL VENTING
When fitted with the factory supplied vent terminal, the MicoFlame can vent up to 50 equivalent feet.
Elbows can range from 5 to 9 feet in equivalent length depending on centerline radius. See Table 1 for
vent sizes.
Boilers may be installed with either a horizontal sidewall vent or vertical roof top terminal. Terminals differ
with each application. Horizontal lengths over 5 feet must be installed using corrosion resistant stainless
steel. Use single wall vent and seal all joints or use pressure rated double wall vent.
Refer to local codes for proper installation and location of vent terminals.
When using sidewall vent, all vent connector seams and joints must be sealed with pressure sensitive
aluminium tape or silicone sealant as specified by the vent manufacturer. Aluminum tape must meet the
provisions of SMACNA AFTS-100-73 Standard.
When venting through unheated spaces with single wall vent, insulation should be wrapped around the
vent pipe to prevent flue gas condensation inside the vent.
Periodically check to ensure that the vent terminal is unobstructed.
6.3
OUTDOOR AIR KIT
When fitted with the factory supplied air inlet ring and air intake terminal, the MicoFlame can draw outdoor
air over an equivalent length of 50 feet. See Table 1 for vent sizes.
Boilers may be installed with either a horizontal sidewall vent or vertical roof top terminal. Terminals differ
with each application.
