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 centreline radius. See Table 2 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. Aluminium 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.
7.3

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 2 for vent sizes.
Boilers may be installed with either a horizontal sidewall vent or vertical roof top terminal. Terminals differ
with each application.
The following applies to outdoor air installations:
1. Use only factory supplied air intake terminal.
2. Periodically check to ensure that air intake is not obstructed.
3. Refer to local codes for proper installation and location of vent terminals. Vertical vent terminal
must be at least 3 feet above the highest point where it is located above the roof of a building and
at least two feet higher than any part of the building within a horizontal distance of ten feet
4. Locate the air intake five feet away from the vent discharge. For sidewall venting locate the air
intake below the vent outlet if possible.
7.4

FILTER KIT

A collar sized as per Table 2 is the standard air inlet configuration for the MicoFlame. A filter kit is
available. The filter is washable and accounts for an additional pressure loss of less than 0.05" W.C.
Highly recommended for dusty environments.
The filter kit can also be provided when using the outdoor air kit.
7.5

STANDARD VENTING

The non-condensing 85% efficient MicoFlame is a category 1 appliance and is approved for venting into a
common standard chimney. If chimney height is much greater than 30 feet or if drafts are in excess of
negative 0.05" W.C., it will be necessary to provide a single acting barometric damper directly above the
vent collar. This damper will ensure smooth light off and minimize standby loss through the boiler. Be
sure to position the damper at least 6 "away from the wall of the vent connector.
