C. CHIMNEY / VENT AND DRAFT CONTROL
1. Draft Requirement – Minimum draft required in the
vent system is -.03" to -.05" W.C. depending on
boiler model, see Table 7.1 (Section 7). This draft is
necessary to provide the necessary draft over fire of
-.01" to -.02" W.C. See discussion in paragraph 5
below regarding draft.
2. Use barometric provided to control draft. Follow
manufacturer's instructions to locate and adjust the
control.
3. Inspect the existing chimney or vent system. Make
sure it is in good condition. Inspect chimney liner
and repair or replace if necessary.
4. The vent system and installation must be in
accordance with the current edition of the American
National Standard ANSI/NFPA 211, "Chimneys,
Fireplaces, Vents, and Solid Fuel Burning
Appliances," or applicable provisions of the local
building codes. See Table 7.1 (Section 7) for typical
chimney size. If the vent system is not sized properly,
the burner may not operate properly. This can cause
poor combustion, sooting and odors to occur.
5. Background Information Regarding Draft:
Modern boilers operate with higher efficiencies than
older boilers. Smaller flueways, as well as bars, pins
and fins are designed into modern boilers to transfer
as much heat as possible from the hot gases to the
water or steam and prevent heat loss up the
chimney. However, these design features result in
higher pressure, or draft loss, in the boiler.
This draft loss must be taken into account when
installing an oil boiler into a new or old chimney.
New chimneys are less likely to have poor draft.
However, they must have sufficient draft to support
combustion. A -.06" draft is desirable and preferred.
Older chimneys may require a replacement liner to
have them perform well enough to support
combustion.
For Example:
The above readings are "cold" readings (before the
boiler and chimney are heated up).
Note also that the higher the firing rate on a unit
which has multiple firing rates, the higher the draft
required. For example, increasing the firing rate 1/4
gallon may increase the draft loss in a unit by
approximately +.01".
D. INSTALLATION SURVEY
For new and existing installations, a Water Installation
Survey or a Steam Installation Survey is available from
P.B. Heat, LLC. The surveys will provide information on
how the boiler works with your specific system and will
provide an overview of boiler system operation in
general.
You can also use this survey to locate system problems
which will have to be corrected. To obtain copies of
these Surveys, contact your PB Heat representative or
download it from PeerlessBoilers.com.
E. PLANNING THE LAYOUT
Prepare sketches and notes of the layout of the
installation. Include boiler location, venting system,
existing piping and wiring. Show existing equipment that
may interfere with installation of new equipment.
An oil-fired unit shall be connected
to a flue having sufficient draft at all
times, to assure safe proper
operation of the unit.

D. WATER BOILER PIPING
1. Refer to the Water Installation Survey and Hydronics
Institute Residential Hydronic Heating
Installation/Design Guide for Guidance.
2. The supply and return connections should be sized
to suit the system.
3. Pipe the supply and return in one of two ways as
shown in Figure 3.3:
a. Pipe the supply from the top of the rear section
and return to the bottom of the front section. Use
the 3/4" tapping in the top of the back section for
air elimination.
b. As an alternative, pipe the supply from the top of
the front section and return to the bottom of the
rear section. Provide air elimination means
within the supply piping.
4. When the return temperature from the system will be
below 150°F on oil boilers for extended periods
(heat pump systems, outdoor reset, snow melt, etc.),
provide piping and controls to protect the boiler from
condensation. Condensation will damage the boiler
and will lead to shortened boiler life and
maintenance problems.
5. If using a Partner indirect fired water heater or other,
see Figure 3.4 for typical piping. Also refer to
additional instructions supplied with the Partner.
6. If the boiler is to be used in conjunction with a
refrigeration system, the chilled medium shall be
piped in parallel with boiler and proper valves
applied to prevent the chilled medium from entering
the boiler. Refer to Figure 3.5.
7. If the boiler is connected to heating coils located in
air handling units, the boiler piping system must be
equipped with flow control valves or other automatic
devices to prevent gravity circulation of the boiler
water during the cooling cycle.

BURNER SETUP & BOILER OPERATION
A. BURNER INSTALLATION
1. The oil burner is supplied with a mounting flange
fixed in position.
2. Mount the burner to the Burner Mounting Plate
(item 3) with four (4) 5/16" studs and nuts provided.
3. Care must be taken when routing the oil lines so not
to interfere with the opening and closing of the
burner mounting plate. Flexible oil lines or flared
copper disconnects with valves (when copper lines
are used) may be installed to assure full opening of
the burner mounting plate when servicing.
4. Oil burner specifications:
For information pertinent to the oil burner such as
nozzle sizing, fuel supply piping, adjusting or
servicing, refer to the charts in this section and the
burner installation manual.
B. BURNER START-UP AND ADJUSTMENT
1. Burner should start automatically when thermostat is
turned up and main boiler service switch is turned
on. If burner does not start, check to be sure there is
oil in the tank and push reset button on burner
control:
Beckett: Square red button.
Carlin: Round red button.
Riello: Round red button inside clear flexible
cover on back of burner cover.
If burner still does not start, contact serviceman.
2. Adjust burner and barometric draft control for
highest CO²(Maximum 13% [EC-03 - EC-05] or
12-1/2% [EC-06]) while maintaining a 0 Smoke and
-.01 to -.02" W.C. draft overfire.
All adjustments must be made using suitable
instruments such as found in a Bacharach
Combustion Test Kit.
3. Burner and boiler can be shut down by turning
down the thermostat and moving the main boiler
service switch to the "off" position.
4. See burner manufacturer's manual for further
information regarding the burner.
C. CHECK BOILER CONTROLS
1. Limit and Operating Controls:
a. Lower the set point of each control until the
burner shuts down. Note that the system pressure
(or temperature) corresponds to the desired set
point.
b. Return the controls to the desired set point.
2. Low Water Cut-off (if used) - consult the
manufacturer's instructions for the low water cut-off
operational check procedure.
D. PURGE AIR FROM THE SYSTEM
(WATER BOILERS ONLY)
1. Purge the system using purge valves, isolating zones
in the process or use system vents. Do not operate
the pump(s) while purging. Pumps will hold air in
the eye of the impeller.
2. Allow the system to reach 180°F and use manual
vents, if installed, to remove any remaining air.
Watch the pressure gauge as the system approaches
180°F. If the pressure exceeds the design operating
pressure, check:
a. Fill valve pressure.
b. Expansion or compression tank operation and
sizing.
5. BURNER SETUP & BOILER OPERATION

BURNER SETUP & BOILER OPERATION
E. CLEAN THE BOILER
(STEAM BOILERS ONLY)
1. Clean the boiler within one week after initial start-up.
Cleaning will be more effective if boiler operates a
day or two to loosen sediment and impurities in
system.
2. Boiler must be cleaned to remove any accumulation
of oil, grease, sludge, etc. in the system. These
substances can cause foaming and surging of boiler
water, producing an unstable water line and water
carryover to system.
3. Connect a skim valve off the 1-1/2 NPT skim tapping
on rear of boiler. See Figure 7.1 (Section 7) for skim
tapping location. Run a 1-1/2 NPT drain line off
skim valve to a point of safe discharge.
4. Provide a means of supplying continuous fresh water
to the boiler for the cleaning process.
5. Use common washing soda, such as Arm and
Hammer Super Washing Soda. Mix 1/2 pound of
soda with water in a 10 quart pail. Pour the mixture
into the boiler through the safety relief valve tapping.
6. Open the skim valve. Fill boiler until water begins to
flow out of the valve.
7. Turn on burner. Allow boiler water to heat up to just
below steaming (180 - 200°F). Do not allow boiler to
steam; steaming mixes up contaminants instead of
floating them at surface.
8. Open make-up water valve to continually feed water
to boiler. Adjust flow to maintain water temperature
at 180 - 200°F.
9. Continue skimming boiler until water flowing from
skim tapping flows clear. This will take some time,
possibly several hours for a dirty system.
10. Turn off burner, close make-up water valve.
11. Drain boiler completely. Refill and drain one or two
times to wash out all washing soda.
12. Remove skim valve and piping. Pipe a nipple and
cap in the skim valve.
Cleaning the boiler requires the use
of very hot water and corrosive
chemicals. Use care when handling
to prevent injury.
WARNING
Do not leave boiler unattended while
firing burner. Operating boiler with
water below minimum permissible
water level may fracture sections.
CAUTION
Do not allow make-up water to flow
too fast. Excessive quantities of cold
water may fracture sections.
CAUTION
If gauge glass becomes dirty more
contaminants have worked loose in
system. Repeat cleaning and
skimming process as needed to
clean system.

Product Safety Information
Refractory Ceramic Fiber Product
This appliance contains materials made from refractory ceramic fibers (RCF). Airborne RCF,
when inhaled, have been classified by the International Agency for Research on Cancer
(IARC), as a possible carcinogen to humans. After the RCF materials have been exposed to
temperatures above 1800°F, they can change into crystalline silica, which has been classified
by the IARC as carcinogenic to humans. If particles become airborne during service or
repair, inhalation of these particles may be hazardous to your health.
Avoid Breathing Fiber Particulates and Dust
Suppliers of RCF recommend the following precautions be taken when handling these
materials:
Precautionary Measures:
Provide adequate ventilation.
Wear a NIOSH/MSHA approved respirator.
Wear long sleeved, loose fitting clothing and gloves to prevent skin contact.

MAINTENANCE
A. GENERAL
1. Check pipes adjacent to cold walls or in unheated
spaces. Insulate and tape them if necessary to be
sure they can't freeze up. Keeping the water moving
at all times will reduce the likelihood of freezing.
2. If there is considerable foreign matter in the boiler
water, the boiler should be shut down and allowed to
cool, then drained and thoroughly flushed out. Drain
the boiler at the drain cock. Pipe the drain cock to a
suitable drain or containment device (if antifreeze is
used). Flush the system to remove remaining matter.
If there is evidence that hard scale has formed on the
internal surfaces, the boiler should be cleaned by
chemical means as prescribed by a qualified water
treatment specialist.
3. There must be no signs of continuous wetness at the
chimney. If signs of continuous wetness are
observed, a qualified service agency must be
consulted to modify the vent configuration to prevent
the formation of condensate, which may damage the
vent pipe.
B. DAILY MAINTENANCE (WITH BOILER
OPERATING)
Daily boiler observation can be performed by the owner.
If any potential problems are found, a qualified installer
or service technician/agency must be notified.
1. Remove any combustible materials, gasoline and
other flammable liquids and substances that generate
flammable vapors from the area where the boiler is
contained. Make certain that the boiler area has
ample air for combustion and ventilation and that
there are no obstructions to the free flow of air to
and from the boiler.
2. Observe general boiler conditions (unusual noises,
vibrations, etc.).
3. Observe operating temperature and/or pressure
gauge on the boiler. Boiler pressure should never be
higher than 5 psi below the rating shown on the
safety relief valve. The valve rating can be found on
the top of the safety relief valve. Boiler temperature
should never be higher than 250°F.
4. Check for water leaks in boiler and system piping.
C. WEEKLY MAINTENANCE (WITH BOILER
OPERATING)
1. Flush float-type low-water cut-off (if used) to remove
sediment from the float bowl as stated in the
manufacturer's instructions.
D. MAINTENANCE OF SAFETY RELIEF
VALVE
1. Check function and maintain safety relief valve as
specified by manufacturer, typically every other
month or every month, per the instructions on the
tag on the safety relief valve.
E. MONTHLY MAINTENANCE (WITH BOILER
OPERATING)
1. Check boiler room floor drains for proper
functioning.
2. Test probe type low-water cut-off (if used) by using
the Push-to-Test Button.
3. Test limit by lowering the limit set point until the
burner shuts down. When proper operation is
confirmed, return the set point to original setting.
4. Follow additional instructions in the Burner Manual
for proving the burner component operation.
F. MAINTENANCE – ANNUAL
TO CLEAN:
1. Remove top jacket panel and flue collector, Item 9.
2. To thoroughly clean the boiler it must be brushed
down from the top and/or left side. Alternatively, for
limited space or minimum clearance to combustible
installations, cleaning the heat exchanger from the
combustion chamber side is acceptable. If unit is
extremely dirty, it may be necessary to brush from all
directions. The target wall is made of a soft ceramic
fiber. Care must be taken not to damage this
material during cleaning.
Turn off power to boiler before
adjusting limit control.
CAUTION
Entire heating system, including
boiler, burner and venting system,
must be inspected at least once a
year by a qualified heating
professional. Boiler is to be cleaned
at least once a year.
NOTICE
Disconnect all power to the burner
before accessing combustion
chamber.
WARNING
Do not use this appliance if any part
has been under water. Improper or
dangerous operation may result.
Immediately call a qualified service
technician to inspect the boiler and
to replace any part of the control
system and any control which has
