GENERAL REQUIREMENTS

REQUIRED ABILITY

Installation or service of this boiler requires ability equivalent to that of a licensed tradesman­ in the field involved. Plumbing, air supply, venting, gas supply, and electrical work are re­quired.

LOCATION

When installing the boiler, consideration must be given to proper location. The location selected should provide adequate­ air supply and be as centralized with the piping system as possible.

REPLACING EXISTING COMMON VENTED BOILER

NOTE: This section does not describe a method for common venting XP units. It describes what must be done when a unit is removed from a common vent system. The XP units require special vent systems and fans for common vent. Contact the factory if you have questions about common venting XP units.

When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for proper venting of the appliances remaining connected to it. At the time of removal of an existing boiler, the following steps should be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.

1.Seal any unused openings in the common venting system.

2.Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion and deficiencies which could cause an unsafe condition.

3.In so far as it is practical, close all building doors and windows and all doors between the space in which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.

4.Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so the appliance will operate continuously.

5.Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle, or smoke from a cigarette, cigar or pipe.

6.After it has been determined that each appliance remaining connected to the common venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas-burning appliance to their previous condition of use.

7.Any improper operation of the common venting system should be corrected so that the installation conforms with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/ or CSA B149.1, Installation Codes. When resizing any portion of the common venting system, the common venting system should be resized to approach the minimum size as determined using the appropriate tables and guidelines in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, Installation Codes.

This boiler is intended for Indoor Installation only, and should not be installed where freezing temperatures or any moisture could damage the external components of the boiler.
