Sidewall Venting

The Peerless WV-DV is designed and built to be vented through a side wall of a building using a
stainless steel concentric vent terminal (4 inch diameter tube inside an 8 inch diameter tube).
Exhaust gases from combustion contain water vapor. During the cooler months of the year, this
water vapor will condense into a visible vapor plume. This water vapor may condense on any
surface near the vent terminal. Care must be taken not to locate the vent terminal where the exhaust
gas, vapor plume and condensation could cause a hazard or a nuisance. Do not locate terminal
under a deck, for instance, as it may create a coating of ice on the deck during the winter months,
as well as shorten the life of the deck materials. Refer to Chapter 4 in this manual for specific
terminal location requirements. Condensate from a side wall vent terminal may also cause paint on
surrounding surfaces to crack and peel. If the boiler is used to heat potable (tap) water, the boiler
will cycle year round.The effects of hot exhaust gases and odors must be taken into consideration
during summer months.

Side wall vented, oil fired appliances may cause soot staining on wall surfaces surrounding their
terminals. To reduce the potential for staining, the boiler must be serviced annually. Soot and scale
must be completely removed from the combustion chamber and cast iron heat exchanger flueways.
See Chapter 7 in this manual. The oil burner must be completely serviced and set up according to
the specifications shown in Chapter 5 of this manual.

PREINSTALLATION

1. PREINSTALLATION

Read carefully, study these instructions before beginning work. It will save time. Study the included drawings. Save these
instructions for reference.

This boiler must be installed by a qualified contractor.

The boiler warranty can be voided if the boiler is not installed, maintained and serviced correctly.

The equipment shall be installed in accordance with those installation regulations in force in the local area
where the installation is to be made, including the current edition of NFPA-31. These shall be carefully followed
in all cases. Authorities having jurisdiction shall be consulted before installations are made.

NOTICE

Do not tamper with boiler or controls.

CAUTION

NEVER BURN GARBAGE OR PAPER IN THE UNIT,
AND NEVER LEAVE COMBUSTIBLE MATERIAL
AROUND IT.

CAUTION

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 been
under water.

BOILER SET-UP

A. SETTING THE BOILER

1. 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. See Section 4-A. “Vent System
Installation,” Page 7, and Figure 4.1.

2. Provide a level foundation, located as close as
possible to the center of the heating system.

3. This boiler is suitable for use on combustible
flooring, provided the boiler is not set on carpet and
a metal drip pan is placed under the appliance.

4. See exploded view (Figure 9.1). After uncrating
boiler and setting it on foundation, open burner
mounting plate (Item 5) and make certain the target
wall (Item 2) is seated in the back of the combustion
chamber. (WV-DV-04) Ceramic fiber blanket base
liner (Item 3) should be lying flat on bottom of
combustion chamber between target wall and burner
mounting plate. Close burner mounting plate.

A. BOILER SUPPLY AND RETURN

1. See Figure 3.1 for suggested piping to the boiler.

2. Make up cold water supply connection to the boiler.

3. Plug all open tappings in the boiler and fill with
water. Apply approximately thirty (30) psi pressure.
Check to make certain that all joints and fittings are
water tight.

4. After all joints and connections have been proven
water tight, remove cold water supply and plugs
from all tappings that are to be used. See Figure 8.1
for tapping locations.

5. Return water piping must be done in such a manner
to allow clearance from the burner mounting plate to
other piping when opening and closing the burner
mounting plate.

3. PIPING AND CONTROLS

PIPING AND CONTROLS

6. The supply and return connections should be sized to
suit the system. A 1-1/2" to 1-1/4" reducing coupling
may be used on the return where the system piping is
1-1/2". The supply should be out of the top of the
back section and return to the bottom of the front
section. There is a 3/4" tapping in the top of the back
section for air elimination.

Figure 3.2

Note: If 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 3.2.

When 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.

B. TANKLESS WATER HEATER

C. INDIRECT-FIRED WATER HEATER

1. If a water boiler is to be used in conjunction with an
indirect-fired water heater refer to Figure 3.4 for
typical piping. Also refer to additional instructions
supplied with tank.

D. SAFETY RELIEF VALVE

1. Remove safety relief valve and 3/4" x 3" nipple from
parts bag. Install nipple and safety relief valve in top
or rear tapping. See Figure 8.1. If rear tapping is
used, installer must supply an elbow so that safety
relief valve is installed in vertical position.

E. CONTROLS

1. For complete information on servicing and
adjustment of controls, refer to the attached control
specification sheets.

Figure 3.3

Figure 3.4

Install mixing valve in hot water supply piping. Water
temperature above 125°F can cause severe burns
instantly or death from scalds.

DANGER

PIPING AND CONTROLS

Pipe the discharge of the safety relief valve to
prevent injury in the event of pressure relief. Pipe the
discharge to a drain. Provide piping that is the same
size as the relief valve.

CAUTION

Note: X-1019R, X-1020R and PP-1011R Coils installed in

WV-DV boilers have internal flow controls installed.
Do not use external flow controls with
these coils.
