Burnham 1100-H4 manual Install Vent Pipe, Burnham Gasketed Vent System

with at least one side open, similar to a joist bay application. Use double wall thimble [Burnham Part No. 8116115 (3”), 100185-01 (4”)] when penetrating a combustible wall.

9.Do not install venting system components on the exterior of the building except as specifically required by these instructions. The vent termination location is restricted as follows:

a.Minimum twelve (12) inches above grade plus normally expected snow accumulation level, or seven (7) feet above grade if located adjacent to public walkway. Do not install over public walkway where local experience indicates appliance flue gas vapor or condensate creates a nuisance or hazard.

b.Minimum three (3) feet above any forced air inlet located within ten (10) feet.

c.Direct Vent - Minimum one (1) foot below, one

(1) foot horizontally from, or one (1) foot above any door, window, or gravity air inlet.

Power Vent - Minimum four (4) feet below, four

(4) feet horizontally from, or four (4) feet above any door, window, or gravity air inlet.

d.Minimum four (4) feet horizontally from electric meters, gas meters, regulators, and relief valves. This distance may be reduced if equipment is protected from damage due to condensation or vapor by enclosure, overhangs, etc.

e.Minimum twelve (12) inches from overhang or corner of building.

10.Enclose vent passing through occupied or unoccupied spaces above the boiler with material having a fire resistance rating of at least equal to the rating of the adjoining floor or ceiling. Maintain minimum clearances to combustible materials. See Figure 1.

Note: For one or two family dwellings, fire resistance rating requirement may not need to be met, but is recommended.

11.Plan venting system to avoid possible contact with plumbing or electrical wires. Start at vent connector on top of boiler and work towards vent terminal.

12.Once a vent pipe manufacturer and system is chosen never mix and match vent systems.

13.If a non-standard length pipe is required:

Gasketed Vent System: The use of the adjustable length pipe (P/N 8116319U) is recommended to complete a non-standard pipe length. This pipe requires a minimum installed length of 12¾ inch and can adjust across a 7 inch gap up to a maximum of 19¾ inch long. (Note for the adjustable pipe the installed length should be measured from the centerline of the bead on the male end of the first pipe to the end of the female pipe excluding the locking band of the second pipe with a single gasket.) Only in the event the adjustable length pipe is not sufficient a standard length pipe may be cut using the procedure outlined below for the Gasket- Less Vent System.

WARNING

Never exceed maximum installed length of 19¾ inches for adjustable length pipe.

Risk of flue gas leakage is possible.

NOTICE

Cut must be square with pipe and filed or sanded smooth before joining. Carefully ensure roundness of cut pipe by hand with gloves before installing. Seal joint with RTV specified in this manual.
