Page 30

WARNING

Remove the baffles if there are any signs of condensation in the chimney or chimney connector. Consult with your local chimney professional for recommendations.

E.Minimum Clearances

See Figure 2 for details regarding clearances to combustibles for the boiler.

F.OPTIONAL AIR INTAKE PIPING INSTALLATION - All air for combustion can be supplied directly to the burner from outdoors providing that the criteria for chimney, vent connector and minimum stack temperature outlined in this section can be maintained. (ONLY AVAILABLE WITH BECKETT BURNER). See Figure 17.

WARNING

Using outdoor air in the middle of winter may result in lower stack temperatures and chimney degradation. Any signs of condensate seepage or discoloration at the base of chimney must be remedied immediately per the details outlined in this section.

Do not reduce size of air intake pipe.

Read, understand and follow combustion air instruction restrictions contained in the Pre- Installation Section of this manual.

1.General

a.Use 4" dia., single wall galvanized metal pipe and fittings available at most heating distributors for air intake piping. Maximum allowable air intake length is 50 equivalent feet. Each elbow is equal to 6 equivalent feet.

WARNING

Do not exceed maximum allowable air intake length.

b.Start at burner. Work toward air intake terminal.

c.Maintain minimum of 1/4 inch per foot slope in horizontal run to air intake terminal. Slope down toward air intake terminal.

d.Seal all joints gas-tight, using silicone caulk or self-adhesive aluminum tape.

2.After determining location, cut a hole in the wall to accept 4 inch air intake pipe. See Figure 15.

3.Remove the metal knockout in right side of burner cover. Install Burnham Inlet Air Accessory Kit, Part

Number 611280031.

4.Mount the Vacuum Relief Valve Tee Assembly (P/N 8116268 included with Kit) or 90° elbow into the burner inlet ring. See Figure 16.

a.Secure with at least three (3) sheet metal screws evenly spaced around the burner inlet ring.

b.Assemble the vacuum relief valve balance weight onto the gate. Refer to the vacuum relief valve manufacturer's instructions.
