Overview

The AERClean Filtration System assembly (P/N 29161) is available for installation to the com­bustion intake duct of the the Benchmark Low NOx Series boilers to prevent particulate air-borne
debris from entering the air fuel valve, burner, blower, and other internal components. The AER­Clean Filtration System is for use in boiler installations drawing air directly from the boiler room.
Advantages of using the filter include:

• Consistent performance in dusty environments.

• Prevention of unnecessary and unplanned service expenses.

• Easily accessed filters for inspection, replacement, or even cleaning.

Installation differs between the 1.5/2.0 and 3.0 models and each is treated seperately in the ap­propriate section. Optional kits include a pressure gauge and a pressure switch. Several filter op­tions are also available (see page 6).

In the BMK3.0LN boilers, the

combustion air intake duct as-

sembly is located at rear and be-

low the top surface. It is connect-

ed to the air fuel valve and exits

out of the boiler top section. The

iris-elbow comprises the lower L-

shaped duct which contains the

iris aperature.

Place lock collar on unit top and position over existing access opening, leaving

space for the reattachment of side access panel. Attach collar to boiler top using

four kit screws (4).

Next, slide the filter housing tube through the collar. Allow sufficient space (over

20”) at front of filter housing to allow easy replacement of air filter through the ac-

cess door. Use four sheet metal screws to attach tube section to the collar (5).

STEP 1:

Remove Hose-Camp

STEP 2:

Loosen and remove the hose clamp (1) from hose connection and remove
foil tape (2). Remove nuts affixed to existing screen cover and then remove screen
cover from the top of boiler (3).

Insert filter housing into the lock collar. You may use two 2”x4” wood pieces (approx.
8” long) to help keep the filter housing vertically oriented (4), so that collar remains
proper distance above top surface until affixed with screws. Ensure filter is oriented
correctly wirh 20” of clearence in front of the filter access door to enable easy filter
replacement. The air filter assembly also requires at least 2” of headroom above it
for sufficient air intake.

Install the filter holder to the lock collar with kit screws (5). Next, slip hose assembly
upward onto collar. It may be a tight fit. Make sure that the 6” hose is not kinked.

After the hose assembly is connected to filter, reapply new aluminum adhesive tape
to seal any leaks (6). Once tape is applied, replace hose clamp and tighten to se­curely attach hose assembly to the filter housing.
