BBOOIILLEERR SSHHIIPPMMEENNTT::
Each boiler is shipped in a single
carton. There is a vent damper packed separately with
the boiler (for model R-300 vent damper is optional)
For Canada, the installation must be in accordance with
Standards CAN/CGA-B149 (.1 or .2) Installation Codes
for Gas Burning Appliances and Equipment and with
Standard C.S.A. C22.1 Canadian Electrical Code, Part 1
and Part 2, and/or local codes.
The following terms are used throughout this manual to bring attention to the presence of potential hazards or to
important information concerning the product:

(a space with
a volume of less than 50 cubic feet per 1000 Btu/hr of
gas input for all fuel burning equipment) or building construction is unusually tight, adequate air for combustion
must be provided by two openings: one located about 6”
minimum free area of one square inch per 1000 Btu/hr of
gas input.
1. Unpack jacket parts from carton and check that quantity is correct: two side panels, one rear panel, one left
top panel and one right top panel (see Figure 1.3).
2. Stand left and right side panels in place and fasten to
front panel with screws provided. Fasten side panels to
rear panel in same manner.
3. Lock left and right halves of top panel together and fasten to side panels with screws provided.
For systems using a circulator on the return as either a
single zone, or multiple zones with zone valves, install a
system bypass line between the supply and return on the
suction side of the circulator (see Figure 1.6). Install a
etering valve in this bypass line to regulate the amount
m
of flow that will be diverted to the return. A plug valve
offers the best control for this application. Although other
valves may be less expensive, a plug valve will be easier
to set accurately.
In the absence of a flow indicator, set the metering valve
using temperature as a guide. The accompanying diagram suggests one scenario. This addition requires only
two tees, a plug valve, and a small amount of pipe and
offers the simplest approach to reliably control condensation. For this system and those that follow, be aware that
you are using a percentage of the pump capacity to
blend, but the friction loss for the entire pump flow has
been reduced. In most cases, the standard pump packaged with the boiler has enough capacity to feed the
baseboard distribution system and the bypass line.
PPUUMMPPAAWWAAYYBBYYPPAASSS
S
For systems that use a single circulator to pump away
from the boiler, the bypass should be installed on the discharge side of the circulator (see Figure 1.7). Full temperature water supplies the baseboard distribution system as before. Half of the circulator’s volume moves
through the bypass, blending and heating the cooler
return water. Again, the cost of installing the bypass is
small and setting it by temperature can be accomplished
with a contact thermometer.
FIGURE 1.6
PPUUMMPPEEDD BBLLEENND
D
An additional circulator can also be used to provide a
return water temperature blend. This method works well
with systems with multiple zones with circulators (see
Figure 1.8). The dedicated bypass circulator provides a
strong blending flow without diminishing the flow available to any heating zone. Any residentially sized circulator is adequate for this purpose.
Each of these bypass solutions also has the added benefit of increasing circulation in the boiler which will maxi
mize tankless coil output and increase the accuracy of
temperature sensing controls.

S
An alternative for existing systems experiencing condensation that does not require re-piping the boiler utilizes a
reverse acting aquastat, one that makes on temperature
ise. This approach works best in single zone systems.
r
Wired in series with the circulator, this control holds the circulator off until the boiler reaches an acceptable temperature and then starts system circulation (see Figure 1.9).
he most commonly available reverse acting aquastat is
T
a Honeywell L4006B. The aquastat should be mounted in
an immersion well directly installed in the boiler. The use
of heat conductive grease (Honeywell part # 972545) in
the immersion well is strongly recommended for fast and
accurate temperature response. Set this adjustable
aquastat to make at no less than 130° F. While this
method can cause the circulator to cycle more frequently,
setting the aquastat’s differential to the maximum (2530°F) will minimize short cycling.
If a hot water boiler is installed in connection with a water
chiller, the chilled water must be piped in parallel with the
boiler, using appropriate valves to prevent the chilled
medium from entering the boiler (see Figure 1.10). When
boilers are connected to heating coils located in air handling units where they may be exposed to refrigerated air
circulation, such boiler piping system shall be equipped
with flow-control valves or other means to prevent gravity circulation of the boiler water during the cooling cycle.

3. Close valves “C” and “D”. Open valve “A”.
When water runs out of the hose in a steady

1. Install draft hood on boiler. If draft hood shroud has a
hole near the relief opening, mount draft hood so hole
faces to the front of the boiler.
2. R-C boilers are equipped with factory-mounted spill
switch harness/mounting bracket as-sembly; spill switch
is provided in bag on boiler front.
3. Install mounting bracket on outside surface of draft

hole in shroud (on outside surface) with the screws provided.
2. Visually inspect the venting system for proper size and horizontal pitch and determine
there is no blockage or restriction, leakage,
corrosion and other deficiencies which could
cause an unsafe condition.
3. Insofar as is practical, close all building
doors and windows and all doors between the

maximum speed. Do not operate a summer
exhaust fan. Close fireplace dampers.
4. Place in operation the appliance being in-spected. Follow the lighting instructions. Ad-just thermostat so appliance will operate continuously
.
5. Test for spillage at draft hood relief opening
after 5 minutes of main burner operation. Use

of the local building codes.
Vent connectors serving appliances vented by natural draft
shall not be connected into any portion of mechanical draft systems operating under positive pressure.
When two or more appliances vent into a common flue, the
area of the common flue should be at least equal to the area of
the largest flue plus 50% of the areas of the additional flue or
vent connectors.

7. Any improper operation of the common venting system should be corrected so installation
conforms with the National Fuel Gas Code,
ANSI Z223.1-latest edition. 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 in Appendix G in the National Fuel Gas Code, ANSI
Z223.1-latest edition. For Canada, the provisions of CAN/CGA
B149(.1 or .2) shall apply.
Chimney condition is of paramount importance for a safe and efficient boiler
installation.
All installations must include a chimney inspection
by a qualified individual or agency. Chimney construction materials must be compatible with the fuel being used.
Particular attention should be paid on all oil-to-gas conversions.
Soot may have accumulated in chimney and/or degraded chim
ney liner. Most utilities require complete chimney cleaning.
Others may require installation of new liner, spill switches or
other chimney upgrades. Check with local utility for required
safety precautions.
Boiler Model R-180C is to be installed. Distance from existing gas meter to installation site is 20 ft. What
pipe size must be used? Local utility indicates heating value of natural gas being supplied is 1020 Btu per cu.ft.
Determine cubic feet of gas per hour for above boiler model:
118800,,000000 BBttuu ppeerr hhoouur
r
= 176.4 cu.ft. per hour
1020 Btu per cu.ft.
1. Find 20 ft. in upper portion of the table for natural gas under “Length of Pipe, Feet” heading.
2. Moving down the column, match required capacity. Higher capacity acceptable. In our case it is 190 cu.ft.
3. Move to left-hand column “Nominal Iron Pipe Size, Inches”; read required pipe size. In our case it is 3/4”.
For any pressure testing in excess of 1/2 psi, the boiler
and its individual shutoff valve must be isolated from the
piping system by disconnecting them and capping the
outlet(s). For any pressure testing equal to or less than
1/2 psi, the boiler must be isolated from the piping system by closing its manual shutoff valve.
T
.
Minimum pressure required at the gas valve inlet is 5”
W.C. for natural gas and 11” W.C. for propane. Maximum
pressure allowable at the gas valve inlet is 12” W.C. If the
gas pressure is above this limit, a pressure regulator
must be installed. If the gas pressure is below these limits, contact the local utility.
All electrical wiring must be in accordance with requirements of authority having jurisdiction or, in absence of
such requirements, to National Electric Code NFPA-70latest edition. If external source is utilized, boiler must be
