Information and specications outlined in this manual in effect at the
time of printing of this manual. ECR International reserves the right to
discontinue, change specications or system design at any time without
notice and without incurring any obligation, whatsoever.
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.

may result in minor or moderate injury.
!
NOTICE
Used to address practices not related to personal
injury.
WARNING
Installing or venting a boiler or any other gas
appliance with improper methods or materials could
result in death or serious injury due to re or to
asphyxiation from poisonous gases such as carbon
monoxide which is odorless and invisible.
!
WARNING
Fire, explosion, asphyxiation hazard. Keep boiler
area clear and free from combustible materials,
gasoline and other ammable vapors and liquids.
Modication, substitution or elimination of factory
equipped, supplied or specied components could
result in death or serious injury.
!
General
Boiler and venting installation shall be completed by
qualied agency.
WARNING
Fire, explosion, asphyxiation and electrical shock
hazard. Improper installation could result in death
or serious injury. Read this manual and understand
all requirements before beginning installation.
!
Become familiar with symbols identifying potential
hazards.
This is the safety alert symbol. Symbol alerts you to
potential personal injury hazards. Obey all safety messages
following this symbol to avoid possible injury or death.
Installation shall conform to requirements of
authority having jurisdiction or in absence of such
requirements to the National Fuel Gas Code,
ANSI Z223.1/NFPA 54.
Where required by authority having jurisdiction,
installation shall conform to Standard for Controls
and Safety Devices for Automatically Fired Boilers,
ANSI/ASME CSD-1. Controls can be added to make
this boiler CSD-1 compliant. Check with your local
codes for requirements.
Requirements for Commonwealth of Massachusetts:
Boiler installation must conform to Commonwealth of
Massachusetts code 248 CMR which includes but is
not limited to installation by licensed plumber or gas
tter.

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 oors only. For installation on
combustible ooring, special base must be used. (See
Replacement Parts Manual.)
4.
Use metal shims under boiler base legs for 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 inltration does not provide necessary
air.“Fresh Air for Combustion” on page 12.
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 13.

DANGER
Burn, scald hazard. Pressuretrol must be installed
by a qualied service agency in accordance with
manufacturer’s instructions, all applicable codes and
requirements of authority having jurisdiction. Failure to
follow the information in these instructions exactly will
result in death or serious injury. Qualied service agency
is responsible for proper installation.

LOCATING THE BOILER
Pressuretrol Assembly
Installation Instructions: See Figure 4.
1.
Attach pressuretrol assembly (A) to site glass
assembly, using proper pipe sealant.
2.
Remove pressuretrol cover.
3.
Route wire harness through black plastic bushing (B).
4.
Attach two wires. Wires are not polarity sensitive, can
place on either terminal.
5.
Replace pressuretrol cover.

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 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 5 and Warning on Page 8.
• 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 as
shown in Figure 6b , Page 10.
• 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 8 page 11. 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 6a and 6b page 10.
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.
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 4 and Figure
7 page 11.
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.
