3.0 FURNACE INSTALLATION
GAS PIPING
Gas piping must conform to local requirements.
Install according to the applicable code such as NATIONAL FUEL GAS CODE ANDSI
Z223.1/NFPA 54 AND/OR NATIONAL GAS AND PROPANE INSTALLATION CODE
CAN/CSA B149.1.
The gas piping must be installed between the gas meter and the combination gas valve
(located upstream of the Riello gas burner on the furnace. The gas valve has a knob acting as
a shut-off valve to stop gas flow. It is recommended to install a manual shut-off valve upstream
of the gas valve to facilitate service of the gas valve. The gas valve also has pressure tapping
for inlet pressure as well as outlet pressure. The outlet pressure of the gas valve is also
referred as manifold pressure in this manual.
If local codes allow the use of a flexible gas appliance connector, always use a new
listed connector. Do not use a connector which has previously serviced another gas
appliance
WARNING:
•Connect from the gas supply to the burner combination gas valve inlet using new, clean
black iron pipe and malleable iron fittings only. Do not use copper, brass, cast iron or
galvanized pipe or fittings.
•Provide support for gas piping. Do not rest weight of piping on burner gas valve.
•Apply pipe dope sparingly at all joints. Use only pipe dope listed for use with propane
gas. Do not use pipe sealing tape. In doubt consult CSA B149.1 or NFPA 54 or the
authorities having jurisdiction.
•Do not hold gas valve with a pipe wrench. Use crescent wrench or other smooth jawed
device. Do not over-tighten.
•Failure to comply with above could result in severe personal injury, death or
substantial property damage.
1. If possible, install a new gas line directly from the gas meter. If you are using an existing
gas line, verify it is clean and in good condition and verify it is large enough to handle the
load of all connected appliances. See the table below for guidance on pipe sizes.
2. When branching from a common gas line, do not tap from the bottom or horizontal sections,
only from the side or top.
3. Install a main manual shutoff valve, sediment trap and ground joint union near the burner
combination gas valve connection as shown below.

9
GAS SUPPLY PRESSURE
•Maximum supply pressure: 13 inches W.C.
•Minimum supply pressure: 7” inches W.C.
•
WARNING:
•Do not expose the combination gas valve to gas pressures in excess of 14” W.C. The
valve has a safety mechanism that interrupt the flow of gas over 14” W.C. In any event
higher pressure could damage the valve seat, resulting in potentially hazardous
conditions. When pressure testing at higher pressures, disconnect burner from gas line
before testing.

10
•If the gas supply pressure can exceed 14 inches of water column at any time, you must
install a lockup type gas pressure regulator in the gas supply piping, ahead of the main
manual gas valve on the burner.
•The furnace and its gas connections must be leak tested before placing the boiler in
operation.
•Enough combustion air should be provided to the gas-fired furnace in accordance with
the section “Air for combustion and ventilation” of the National Fuel Gas Code ANSI
Z223.1/NFPA 54 or clause 8,2, 8,3 or 8.4 of Natural gas and Propane installation code
CAN/CSA B149.1, or applicable provisions of the local building codes.

WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected to the venting
system being placed into operation could result in carbon monoxide poisoning or
death.
When an existing furnace is removed from a common venting system, the common venting
system is likely to be too large for proper venting of the appliances connected to it. At the time
of removal of the existing furnace, the following steps shall be followed with EACH appliance
remaining connected to the common venting system, while the other appliances remaining
connected to the common venting system are not in operation:
1. Seal any unused openings in the venting system.
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 operation.
3. Insofar as is practical, close all building doors and windows and all doors between the
space in which the appliances remaining connected to the common venting system are
located and other spaces of the building. Turn on clothes dryer and any appliance not
connected to the common venting system. Turn on any exhaust fans, such as range
hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate
a summer exhaust fan. Close fireplace dampers.
4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust
thermostat operation so appliance will operate continuously.

12
5. Test for spillage at the draft regulator outlet / draft hood opening after 5 minutes of main
burner operation. Use the flame of a match or candle, or smoke from a cigarette, cigar,
or pipe.
6. After it has been determined that each appliance remaining connected to the common
venting system properly vents when tested as outlined above, return doors, windows
exhaust fans, fireplace dampers and any other gas-burning appliance to their previous
condition of use.
7. Any improper operation of the common venting system should be corrected so the
installation conforms with the National fuel gas code ANSI Z223.1/NFPA 54 and/or the
Natural gas and propane installation code CAN/CSA B149.1. When resizing any portion
of the common venting system, the common venting system should be resized to
approach the minimum size as determined by the appropriate tables in chapter 13 of the
National fuel gas code ANSI Z223.1/NFPA 54 and/or the Natural gas and propane
installation code CAN/CSA B149.1.
•Vent installations shall be in accordance with Part 10, Venting of Equipment, and
Part 13, Sizing of Category I Venting Systems, CSA B199.1, of the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 , and/or Section 7, Venting Systems and Air
Supply for Appliances, and Appendix C, Vent Sizing Tables for Category I Natural

4.0 ACCESSORIES INSTALLATION
BLOCKED VENT SWITCH (BVSO) FOR CANADIAN APPLICATION ONLY
Oil-fired appliances installed in Canada require a blocked vent switch system when installed on
a chimney. A safety switch is included with the furnace to perform this function. It is the
installer’s responsibility to install the switch in accordance with the instructions provided. Not
applicable for direct vent systems. Field Controls Model: WMO-1 (Manual Reset)
Switch Operation
Blocked vent switches are flue gas safety devices for detecting spillage of flue gases due to a
blocked flue or inadequate draft. After detecting a problem, the switch de-energizes the
system’s burner control.
NEVER reset the switch unless the cause of the blockage has been corrected.
Installation
1) Drill a 5/8” hole in to the flue vent pipe near the appliance breech connection.
2) This hole must be before the draft regulator, vertically or horizontally.
3) Remove one of the securing nuts from the threaded tube of the safety switch.
4) Tighten the other securing nut onto the pipe as far as possible (Figure 1).
5) Insert the threaded tube end into the pierced hole of the flue vent pipe.
6) Install the securing nut on the safety switch tube, which protrudes into the flue vent pipe.
Tighten the nut securely (Figure 1).
Figure 1 – Illustration Granby Industries Figure 2 - BVSO wiring diagram
Wiring Instructions (BVSO)
Caution: Disconnect the electrical power when wiring the unit.
Wire the blocked vent switch in accordance with The National Electrical Code and applicable
local codes. Wire the safety switch (BVSO) in series with the thermostat and the fan timer
relay control (Figure 2).

16
System Test Procedure (BVSO)
1) With the power re-established, block the chimney or vent pipe downstream of the switch.
2) Adjust the thermostat to call for heat.
3) Once the heating system has started the blocked vent switch should shut down the burner
within 10 minutes or sooner.
4) Once the system has cooled, the blocked vent switch can manually be reset.
5) This procedure should be tested a second time.
6) After testing the blocked vent switch the chimney should be cleared of obstruction and the
heating system should be tested over a long run cycle.
If the block vent switch shuts down the system, check to ensure there is enough draft in the
chimney and venting pipes.
AIR CONDITIONING
An air conditioning coil may be installed on the supply side only. Coils installed on the return
side will cause condensation on the heat exchanger; this will shorten the heat exchanger life
and may cause products of combustion to enter the house. Wire as per wiring label and
diagram. Height of the coil above the unit supply shall be at least 4” (102 mm) for the
ECLIPSE and 0’’ for the GEMINI.
