C 85-340 Introduction - Installation & Operation Instructions │ Caprice

Direct Vent Applications

There are four Caprice models, C95-C150, certified for installation as a Direct Vent boiler. This balanced flue
system requires a special venting system in order to pressurize and essentially equalize the inlet and outlet
pressure to ensure normal operation. Refer to section “General Venting” and “Specifications” for more details on
Direct Vent applications and termination kits.

Balanced Flue Applications - Models C95-150 are also certified as Direct Vent boilers

and must be ordered as such. Balance flue systems must use the NTI approved venting
system. Note that the Direct Vent Terminal and Insulated Flex Pipe are sold separately (see Table 7-2 Direct
Vent Kit Components for more details). This “Special Venting System” is designed for pressurized venting with
NTI Direct Vent boilers. The exhaust gases must be piped directly to the outdoors using the vent materials and
rules outlined in these instructions. Failure to follow these instructions will result in serious injury or death.

Table 1-2 Caprice Boiler Packages (Direct Vent)

Manufacturer’s Instructions - For complete instructions on installation and control
operations, refer to the manufacturer’s instructions included with the Fuel Smart

HydroStat 3250, Burner Package, and Direct Vent Terminal.

Nozzle Sizes - The nozzle sent with each respective boiler burner kit is for the minimum

firing rate specified for that burner. To obtain a different firing rate, replace the factory
supplied nozzle with the appropriate nozzle that meets the desired output. Refer to Tables 2-3 to 2-4 in Section 2.0
for nozzle specifications and performance ratings for Direct Vent boilers.

Intakes/Vents - Failure to keep the Vent and Combustion Air Intake clear of ice, snow,

and other debris may result in property damage, serious injury, or death.

b. Refer to specification Tables 2-1 to 2-4 to determine the appropriate nozzle size for the boiler output. See

“Attention: Nozzle Sizes” in Section 2.0.

c. Riello Burners (extra step required): Mount the burner gasket and burner flange to the boiler. Secure to

the boiler using washers and nuts provided (Figure 4-5). Seal around the burner gasket and the blast tube
ring with high temperature silicone (i.e. 83ml tube of silicone included in the burner kit).

d. Mount prepared burner package to the boiler. Seal around burner flange with high temperature silicone.

Oil Supply Tank and Oil Piping

The oil supply tank and piping should be installed in accordance with the instructions in this manual; the burner
and pump manufacturer’s instructions; National codes NFPA 31 (USA) or CSA B139 (Canada), and local codes.

General Installation Guidelines:

1. Install the oil supply tank as per tank manufacturer’s instructions.

2. Install oil supply piping from the tank to the burner.

3. Recommend installing a low pressure-drop fuel oil filter to prevent burner nozzles plugging at low flow rates.

4. Shut-off valves should be installed to control the flow during operation and to avoid spills during servicing.

5. Oil can be fed from the supply tank by gravity (single pipe system) or by transfer pump (two-pipe lift system).

6. Refer to burner manufacturer’s instructions before installing oil piping systems as some burner packages are

not equipped to work with two-pipe lift systems (i.e. Riello BF5).

7. Connect oil supply piping to the fuel oil pump as per the pump manufacturer’s instructions and system type.

Ceramic Fiber Materials - Before installing the burner, read “Handling Instructions” in

Section 11.0 and the protective measures recommended when handling ceramic materials.

Fuel Oil - Caprice boilers operate with No. 2 oil as their only approved fuel source. DO

NOT USE GASOLINE, CRANKCASE DRAININGS, OR ANY OIL CONTAINING

Combustion Analyzer - To calibrate burner operation, use a calibrated combustion analyzer

capable of measuring CO2 and O2 from oil burning boilers

Smoke Test - All tests must be done with the burner covers or air intakes in place to

simulate normal operation.

Smoke Pump - A reliable, certified smoke pump is required to correctly set up this

equipment.

Avoid Condensation - Due to the high combustion efficiencies and low stack gas

temperatures, great care must be taken to ensure the chimney isn’t subjected to flue gas

Combustion Air Settings - Refer to Section 10.0 Installation Checklist for instruction

regarding adjusting combustion air settings.

Pipe Dope / Teflon Tape - DO NOT use on direct oil connection to the fuel pump.

Failure to follow instructions may cause valve failure and dangerous operating conditions.

5.0 GENERAL VENTING
Natural Draft Applications

Caprice models C85-340 are certified as Natural Draft boilers. The Natural Draft installation draws combustion
air from the room and uses the stack effect and draft system to exhaust flue gases using a chimney.

Air Supply - Allowances for combustion air must be supplied to the appliance space, due to the fact that the
heating appliance consumes large volumes of combustion air. In most instances, a permanent opening with an
unobstructed or “free area” of 1 square inch for every 1000 BTU’s of input will provide a sufficient amount of
combustion air for the boiler to operate properly. If the building is fairly new and relatively air tight, compensate
for the air tightness by using a “free area” that is 15% larger that what was calculated above. Do not place the
boiler in, or adjacent to, a room where an exhaust fan is operating. Refer to “Combustion Air” in Section 6.0
Natural Draft Applications for more details. Installation must comply with Standard CSA B139 (Canada) and
NFPA 31 (USA).

Stack Draft - Sufficient draft by natural or mechanical means is necessary for ensuring optimal and consistent
operation. The appliance should have a stack draft sufficient to support stable operation. See Draft Settings
(Natural Draft).

condensation. The exhaust gas temperature where the flue pipe enters the chimney must be a minimum of 240oF
or condensation may occur.

Draft Regulator - A draft regulator must be used and set to regulate the draft of the boiler. Make sure that the
damper is free to operate without sticking, for this will affect the boiler’s combustion system. It is important that
the draft be adequate because poor draft conditions will cause poor operation and a possible hazardous condition.

for proper operation. Due to the design of the Caprice it may operate at a positive over fire pressure up to +.20 at a

-.03 draft.

Direct Vent Applications

Caprice models C85-150 are also certified for direct vent applications. The Direct Vent installation uses a special
venting system where exhaust gases are vented directly to the outside using a special venting system which
equalizes the pressure between the air inlet and the flue outlet resulting in a balanced flue system. Refer to Section

7.0 Direct Vent Applications for more details. Installation must comply with Standard CSA B139 (Canada) and
NFPA 31 (USA).

designed to operate with a maximum stack draft of 0.25” w.c and a maximum over fire draft of 0.33” w.c. when
little or no wind is present. In extreme wind conditions, the maximum stack draft is 0.35” w.c. and the maximum
over fire draft is 0.45” w.c.

Avoiding Condensation - Due to the high combustion efficiencies and low stack gas

temperatures, great care must be taken to ensure that the chimney isn’t subjected to gas

Draft Settings (Natural Draft) - The Caprice is designed to operate with a -.03” w.c.
