Installation & Operation Manual

3 General venting (continued)

Install vent and combustion air piping

￿DANGER The Knight XL must be vented and supplied with combustion and ventilation

air as described in this section. Ensure the vent and air piping and the combustion air supply comply with these instructions regarding vent system, air system, and combustion air quality. See also Section 1 of this manual.

Inspect finished vent and air piping thoroughly to ensure all are airtight and comply with the instructions provided and with all requirements of applicable codes.

Failure to provide a properly installed vent and air system will cause severe personal injury or death.

PVC/CPVC vent piping materials

￿WARNING Use only the materials listed in Table 3A (pg. 18) for vent pipe, and fittings. Failure

to comply could result in severe personal injury, death, or substantial property damage.

NOTICE

Installation must comply with local

requirements and with the National Fuel

 

Gas Code, ANSI Z223.1 for U.S. installations

 

or CSA B149.1 for Canadian installations.

￿WARNING Insulation should not be used on PVC or CPVC venting materials. The use of

insulation will cause increased vent wall temperatures, which could result in vent pipe failure.

Requirements for installation in Canada

1.Installations must be made with a vent pipe system certified to ULC-S636.

IPEX is an approved vent manufacturer in Canada supplying vent material listed to ULC-S636.

2.The first three (3) feet of plastic vent pipe from the appliance flue outlet must be readily accessible for visual inspection.

3.The components of the certified vent system must not be interchanged with other vent systems or unlisted pipe/fittings. For concentric vent installations, the inner vent tube must be replaced with field supplied certifiedvent material to comply with this requirement.

￿CAUTION Improper installation of PVC or CPVC systems may result in injury or death.

Installing vent or air piping

￿WARNING

NOTICE

For closet and alcove installations, CPVC or stainless steel material MUST BE used in a closet/alcove structure. Failure to follow this warning could result in fire, personal injury, or death.

All PVC vent pipes must be glued, properly supported, and the exhaust must be pitched a minimum of a 1/4 inch per foot back to the boiler (to allow drainage of condensate).

NOTICE

Use only cleaners, primers, and solvents that

are approved for the materials which are

 

joined together.

1.

Work from the boiler to vent or air termination. Do not

 

exceed the lengths given in this manual for the air or vent

 

piping.

2.

Cut pipe to the required lengths and deburr the inside and

 

outside of the pipe ends.

￿WARNING

This appliance requires a special venting system. The vent connection to the appliance must be made with the starter CPVC pipe section provided with the appliance if PVC/ CPVC vent is to be used. For stainless steel venting use an adapter from Table 3B (page

20)that corresponds with the intended vent manufacturer to be used and discard the CPVC starter piece. The field provided vent fittings must be cemented to the CPVC pipe section using an “All Purpose Cement” suitable for PVC and CPVC pipe. Use only the vent materials, primer, and cement specified in this manual to make the vent connections. Failure to follow this warning could result in fire, personal injury, or death.

3.

Chamfer outside of each pipe end to ensure even cement

 

distribution when joining.

4.

Clean all pipe ends and fittings using a clean dry rag.

 

(Moisture will retard curing and dirt or grease will prevent

 

adhesion.)

5.

Dry fit vent or air piping to ensure proper fit up before

 

assembling any joint. The pipe should go a third to

 

two-thirds into the fitting to ensure proper sealing after

 

cement is applied.
