In addition where required by the authority having juris-

diction, the installation must conform to American

Society of Mechanical Engineers Safety Code for

Controls and Safety Devices for Automatically Fired

Boilers, No. CSD-1.

WARNING

This boiler, gas piping and accessories must be

installed, connected, serviced and repaired by a

trained, experienced service technician, familiar with all

precautions required for gas-fired equipment and

licensed or otherwise qualified, in compliance with the

authority having jurisdiction.

WARNING

The venting system of this boiler is under positive pres-

sure. Leakage from this system can be hazardous and if

not avoided can result in death or serious injury. In addition

to the recommendations within this manual and the User’s

Information Manual, the venting system, from the flue col-

lector to the outdoor discharge, must be carefully checked

annually by a qualified service agency.

This manual must be left with owner and should be hung on

or adjacent to the boiler for reference.

Lynx 5 CONTAMINATION PREVENTION The combustion air supply must not be susceptible to contamination sources, whether the combustion air comes from the interior or exterior of the building. Contaminated air can cause corrosion or other damage to the heat exchanger and components of the boiler, causing failure of these parts or unsafe operation.
PAGE 6
Lynx MOUNTING THE BOILER ON A WALL Be sure that the wall is vertically plumb and capable of carrying the weight of the boiler and the system piping, when full of water. See page 2 for the boiler weight. 4. Lift the boiler up against the wall, with the top edge of the jacket slightly above the wall bracket tabs.

Lynx 9 6. The Lynx boiler is equipped with a built-in condensation drain and trap. The trap must be filled with water. DO NOT operate the boiler without filling the trap with water to prevent flue gas discharge into space. The drain must dispose of possibly large quantities of condensate, which may require a neutralizing system. Refer to the “Condensate Drainage” section of this manual. No additional condensation drain and trap is required on the vent piping system itself. 7.

VENT/AIR INTAKE TERMINATION FOR PVC/CPVC, OR POLYPROPYLENE VENTING INSTALLATION (P# 840802000) This termination is designed specifically for 3” diameter PVC, CPVC Schedule 40 or polypropylene pipe to be used as the vent and air intake piping material, only. It can be used on a combustible wall, provided the 1” minimum clearance of the vent pipe to any combustible surface is maintained. 1. Termination must be installed horizontally.

Lynx 17 B. DIRECT VENT - VENTING AND AIR INTAKE THROUGH A ROOF Figure 14 shows typical vertical venting. The vent pipe must pass through the ceiling, floor and the roof vertically through a 6” minimum diameter cutout. A fire stop is required for each ceiling and floor penetration. For roof passage an appropriate UL listed roof flashing must be used. The vertical vent piping must terminate with a screened straight termination. The air intake termination should be a screened 180˚ elbow facing down.
PAGE 18
VENTING AND AIR INTAKE SYSTEM REGULAR INSPECTION A. Inspect the system regularly for condensation, corrosion, sagging and/or physical damage. A qualified professional should service the boiler annually and include such an inspection at that time. The homeowner should look over the system monthly for damage, water stains, any signs of rust, other corrosions or separation of the vent and air intake piping (if direct-vent). B.

Lynx 19 At 30 ft. length of pipe, match required capacity from table on this page (choose higher capacity, in this case is 152 cu. ft. per hour). Required pipe size is 3⁄4". Improper gas pipe sizing will result in flame outages, insufficient heat and other installation difficulties. For more information and also if other appliances are to be attached to the piping system, see Appendix C of National Fuel Gas Code ANSI Z223.1-latest edition. C.
