SPECIFICATIONS INFRARED BROILER
ELECTRICITY SUPPLY
Free-standing models (B32N-170, B32N-171, and B32N-270) have a 7-foot (2134 mm) power cord with a grounded
plug to supply 50Hz or 60Hz single-phase 120VAC electric power. Model B32N-171 units with the optional electric
heating element for the warming oven also have a terminal block for connection to a single-phase 208/240V source.
Sectional-base models (B32D-171 and B32A-171) can be ordered to use either 120V power or 208/240V power.
Units wired for 120V power have a 7-foot (2134 mm) power cord with a grounded plug to supply 50Hz or 60Hz singlephase 120VAC electric power. Units wired for 208/240V power have a junction-box for connecting wires to a singlephase 208/240V source.
The appliance, when installed, must be electrically grounded in accordance with local codes, or in the absence of
local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as
applicable. An electrical diagram is located on the inside of the oven kick plate of sectional-base models, and behind
the air-intake grill of free-standing models (see Figure 1 on page 3).
VENTILATION
WARNING
Improper ventilation can result in personal injury or death. Ventilation which fails to properly remove flue products
can cause headaches, drowsiness, nausea, or could result in death.
All units must be installed in such a manner that the flow of combustion and ventilation air is not obstructed.
Provisions for adequate air supply must be provided.
NOTICE
Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be covered by the
warranty.
Do not obstruct the front or rear of the unit since combustion air enters through these areas. Be sure to inspect
and clean the ventilation system according to the ventilation equipment manufacturer’s instructions.
If a ventilation canopy is used, it is recommended that the canopy extend 6" past the appliance and that the bottom
edge be located 6'6" from the floor. Filters should be installed at an angle of 45° or more from the horizontal. This
position prevents dripping grease and facilitates collecting the run-off grease in a drip pan, unusually installed with a
filter.
A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may
extinguish pilot flames. Fresh air openings approximately equal to the fan area will relieve such a vacuum. The
exhaust fan should be installed at least 2" above the vent opening at the top of the unit.
If the unit is connected directly to an outside flue, a CSA design certified down draft diverter must be installed.
In case of unsatisfactory performance on any appliance, check the appliance with the exhaust fan turned OFF. Do this
only long enough to check whether doing so corrects any problems with equipment performance. Then turn the
exhaust fan back on and let it run to remove any exhaust that may have accumulated during the test.
GAS SUPPLY
Free-standing models (B32N-170, B32N-171, and B32N-270) have a 3/4" rear gas connection with a male NPT
connector. Sectional-base models (B32D-171 and B32A-171) have a 1-1/4" front gas manifold that couples to the
adjacent sectional unit(s), and can be ordered with an optional 1" rear gas connection with a male NPT connector.
Minimum supply pressure is 7" W.C. for natural gas, 11" W.C. for propane. An external pressure regulator and shut
off valve must be provided. If using a flexible-hose gas connection, the I.D. of the hose must not be smaller than the
connector on the unit and must comply with ANSI Z21.69. Provide an adequate means of restraint to prevent undue
strain on the gas connection.
These appliances are design-certified for operation on natural or propane gases. The unit is shipped configured and
adjusted for the type of gas specified by the purchaser. The serial plate indicates the type of gas the unit is equipped
to burn. The appliance should be connected ONLY to the type of gas for which it is equipped.
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance
with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, Natural Gas
Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA-B149.2, as applicable.
PAGE 6 OF 28 OWNER'S MANUAL 1184964
INFRARED BROILER SPECIFICATIONS
An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for
satisfactory performance. Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems
and affect burner operating characteristics. A 1/8" pressure tap is located on the manifold to measure the manifold
pressure. The supply line to the unit should be no smaller than the inside diameter of the pipe on the unit to which it is
connected.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.
All pipe joints and connections must be tested thoroughly for gas leaks. Use only soapy water for testing on all gases.
NEVER use an open flame to check for gas leaks. All connections must be checked for leaks after the unit has been
put into operation. Test pressure should not exceed 14" W.C.

OPERATION INFRARED BROILER
OPERATION
DANGER
EXPLOSION HAZARD
In the event a gas odor is detected, shut down equipment at the main shut off valve. Immediately call the
emergency phone number of your gas supplier.
CAUTION
If the broiler pilots should go out the flow of gas to the broiler burners is NOT interrupted. Consequently, it is the
responsibility of the operator to check the ignition of the burners immediately EVERY TIME the broiler is turned on.
Should ignition fail after 10 seconds, turn off burners, wait 5 minutes, and then try again.
NOTICE
Blodgett Range infrared broilers cook food in about half the time of conventional broilers, so adjust cooking times.
The location of controls and other components are shown in Figure 3 for Model B32N-170, Figure 4 for Model B32N171, Figure 5 for Models B32A-171 and B32D-171, and Figure 6 for Model B32N-270.
LIGHTING AFTER GAS HAS BEEN SHUT OFF
When turning on the main gas supply after it has been shut off, do the following:
1. Make sure that all the control valves and power switches are in the OFF position.
2. Turn on the main gas supply valve(s).
3. Light the standing pilots of each connected appliance.
4. For sectional-base models, light the ovens first, then wait six minutes before lighting the broilers. This allows all
air to be purged from the sectional-range gas piping.
OPERATION OF INFRARED BROILER
Blodgett Range infrared broilers broil in half the time of ordinary broilers. The burners reach operating temperature in
just 90 seconds, and their intense infrared energy quickly heats the food, not the surrounding air. The broiling grid
adjusts to four heights, and rolls out for easy access. A blower delivers fresh, filtered air to prevent smoke and vapors
from affecting broiling efficiency.
The broiler grid is 24-1/2" wide by 28" deep, and rolls out 17-1/4". The front 3" of the grid receives less heat, and so
can be used as a holding area. As food cooks, drippings drain into a collection drawer that is out of the heat zone. To
operate the broiler, do the following:
Each broiler has two control valves. The valve on the left controls the two burners that heat the left side of the broiler,
while the valve on the right controls the two burners than heat the right side of the broiler.
1. Light the constant-burning pilots located near the front of the broiler burners (unless the pilots are already lit).
2. Press the Blower Switch to ON. (The broiler can be safely operated with the blower OFF, but the smoke and
vapors rising off the cooking food will reduce the infrared broiling efficiency.)
3. Turn the burner control(s) to HIGH and visually check that the burners have ignited. When the burners ignite, a
blue flame will cover the surface of the ceramics for 10-15 seconds. Within 30 seconds this haze will disappear
and the ceramics will glow red. The flame on the surface of the ceramics should be barely visible, with practically
no blue haze.
4. If searing the food to mark it with grid marks is desired, before placing food on the rack move the broiler rack to its
highest position and allow the burners to operate for five minutes.
5. Turn the burner control(s) to HIGH or LOW (as appropriate for the food to be cooked).
6. Raise or lower the broiler rack to the height appropriate for the food to be cooked.
PAGE 8 OF 28 OWNER'S MANUAL 1184964
INFRARED BROILER OPERATION
7. Pull out the rack, place food on it, and slide the rack back into the broiler. Remember that the front 3" of the rack
receives less heat so it can be used as a holding area. This holding area is marked by a 1/8" diameter rod.
8. Cook the food for the appropriate time, turning it when appropriate. Periodically check the broiler drippings
drawer(s) and empty if necessary.
9. When done broiling, turn the burner controls and blower switch to OFF. (To keep the broiler grid hot in order to
mark food with sear marks without preheating, turn the burner controls at LOW and move the broiler rack to its
highest position. The blower fan switch can be turned OFF.)
LIGHTING BROILER PILOTS
The pilots should burn continuously unless the broiler is to be completely shut down. The broiler cavity has two pilots,
each near the front of a pair of burners. If the pilots are extinguished, the pilot gas supply is NOT automatically
interrupted. To light the pilots, do the following:
1. Turn the broiler burner valves to OFF.
2. Turn the blower switch to OFF.
3. Turn on the main gas supply to the unit (if not already on).
4. Turn on the manual service valve located on inlet supply line in the blower compartment.
5. Turn on the small valve located behind the plug button, just below the left burner valve.
6. Light the pilots.
OPERATION OF WARMING OVEN
Models B32A-171, B32D-171, and B32N-171 have an overhead warming oven that is heated by flue gases from the
broiler. Operating the broiler only to heat the warming oven is inefficient and so is not recommended. If the optional
electric element was ordered, it can be switched on to heat the warming oven. The warming oven is 25" wide by 25"
deep.
OPERATION OF BASE OVEN
To operate the oven (of models that have an oven base), do the following:
1. Turn the Oven Gas Valve to the OPEN position.
2. Move the Oven Power Switch to the "ON" position. The oven pilot will automatically light, and the oven burner will
come on (if the oven is below the set cooking temperature). The Cooking Light is lit when the power switch is on.
3. On convection-oven models, select the fan speed (HI or LOW) using the Fan-Speed Switch.
4. Select the desired oven cooking temperature using the Cooking Temperature dial.
5. When done cooking using the oven, move the Power Switch to OFF and turn the Oven Gas Valve to OFF.
Cooking tips for using a convection oven are included in the manual for the Saffire Series Sectional Range (1184743).
SHUTDOWN OF BROILER
To place the broiler in a standby state (ready for use), turn the burner control valves and the blower on-off switch to
OFF. The pilots will remain lit.
To completely shut down the range for an extended period (or prior to disconnecting the gas supply), turn OFF the
manual shut-off valves of all gas supply connections to the sectional range. (This will extinguish all pilots.)
