Introduction
Boiler is designed for use in closed heating systems where all steam is returned as condensate and make-up water is minimal. Boiler is not designed for or intended for use in open systems using 100% make-up water.
Prior to Installation
• Verify correct boiler for type of gas being used natural or propane. See Rating Plate.
• Verify boiler size and dimensions. See Figure 1 and Table 1, page 2.
• Verify ratings and capacity data for natural gas. See Table 2.
Installation Requirements
• Supply boiler with correct gas (natural or propane), fresh air for combustion, and suitable electrical supply.
• Connect boiler to adequate venting and piping systems.
• Provide boiler with properly located and adjusted thermostat.
Installation of boiler in building under construction, use precaution to insure clean combustion air supply during construction process. Airborne particulate from construction materials can clog burner ports and cause incomplete combustion and sooting.
Complete all steps for safe and proper heating system operation.

LOCATING THE BOILER
Locating the Boiler
1.
Select level location as centralized with piping system, and as near chimney as possible.
2.
Place crated boiler at selected location. Remove all crate material. Please recycle responsibly.
!
WARNING
Fire hazard. Do not install boiler on combustible ooring or carpeting. Failure to follow these instructions could result in death or serious injury.
3.
Do not install boiler on carpeting. For installation on non-combustible fl oors only. For installation on
combustible fl ooring, special base must be used. (See Replacement Parts Manual.)
4.
Use metal shims under boiler base legs for fi nal leveling if needed.
5.
Install boiler in location that permits satisfactory combustion of gas, proper venting, and maintenance of ambient temperature at safe limits under normal conditions of use. Boiler location should not interfere with proper circulation of air. Introduce outside air if normal infi ltration does not provide necessary air. “Fresh Air for Combustion” on page 11 .
6.
Notify owner to keep air passages free of obstruction. Ventilating and combustion air must enter boiler room without restrictions.

!
WARNING
Asphyxiation, carbon monoxide hazard. Failure to follow these instructions could result in improper combustion and possible leakage of combustion products into the living space.
Follow directions given in Figure 3. Attach draft diverter, and blocked vent switch. Mount vent damper. See "Connecting Vent Damper and Vent Connector" page 12. See Wiring Diagrams pages 24 and 25.

2.
Remove top jacket panel (4 screws).
3.
Slide draft hood over fl ue collector.
4.
Secure with 1 or 2 screws, based on boiler size.
5.
Replace top jacket panel (4 screws).
6.

HYDRONIC PIPING
!
WARNING
Burn or Scald Hazard. Discharge line shall be installed to relief valve outlet connection to avoid burns, scalding, or water damage due to discharge of steam and/or hot water during operation.
Discharge line shall:
• Connect to safety valve outlet. Piped down to safe point of disposal. Check local codes for maximum distance from fl oor or allowable safe point of discharge.
• Pipe size be of equal to or greater than of safety valve outlet over entire length of discharge line.
• Have no intervening shutoff valve between safety valve and discharge to atmosphere. Do not plug or place any obstruction in discharge line.
• Terminate freely to atmosphere where any discharge will be clearly visible and at no risk of freezing.
• Allow complete drainage of valve and discharge line.
• Install safety valve with spindle in vertical position.
• Do not install shutoff valve between boiler and safety valve.
• Support safety valve discharge piping.
• Be short and straight as possible.
• Terminate with plain end, not threaded.
• Constructed of material suitable for exposure to temperatures of 375° F (191°C); or greater.
Refer to local codes and appropriate ASME Boiler and Pressure Vessel Code for additional installation requirements.

HYDRONIC PIPING
Consider near boiler piping as part of the boiler for proper water level control and to produce dry steam.
Correct near boiler piping is crucial to proper operation of boiler and heating system.
Follow these recommendations carefully.
1.
Place boiler in selected location as near chimney as possible.
2.
Install safety valve. Figure 4 and Warning on Page 7.
• Install union, if used, close to safety valve outlet.
• Install elbows close to safety valve outlet and downstream of union (if used).
3.
Boiler is equipped with two 2" supply connections and two 2" return connections, one each on both left and right sides of boiler. Plug unused connections with furnished 2" plug and 2 x ¾ " bushing for drain valve.
4.
When using both supply tappings to pipe system. Figure 5b , Page 9
• Fit headers with header offsets, swing joints, or equip with expansion joints, so thermal expansion and contraction of header does not damage boiler. Do not weld headers.
• Place system takeoffs from header between equalizer and riser to header nearest equalizer. System takeoffs must never be between two risers. If steam main goes in two directions, place two takeoffs from header, one for each main.
5.
Recommended near boiler piping for gravity return systems is shown in Figure 7 page 10. For gravity return systems, bottom of lowest steam carrying pipe, dry return or end of steam main, must be at least 28” above normal water level line on left side of boiler.
6.
Equip all boilers in gravity return systems with Hartford
Loop as shown in Figure 5a and 5b page 9.
7.
Piping vertical risers from boiler to header, risers must be minimum of 24" high above water line..
8.
Steam riser(s) and header shall be 2" pipe size.
9.
Equalizer line shall be minimum 1-1/2" pipe size.
10.
Near boiler piping shall include 2" tee with female adapter and cap located on supply line as shown for skimming (i.e. surface blow-down).
11.
For pumped return systems, follow condensate pump or boiler feed pump manufacturer’s instructions for proper installation and hookup. See Table 3 and Figure 6 page 10.
12.
Connecting cold water supply to water inlet valve, verify clean water supply is available. When water supply is from well or pump, install sand strainer at pump.
