Ventilation of the boiler room must be adequate to provide sufficient air to properly support combustion per the latest revision of the National Fuel Gas Code,
ANSI Z223.1.
When a boiler is located in an unconfined space in a building or conventional construction frame, masonry or metal building, infiltration normally is adequate to provide air for combustion and ventilation. However, if the equipment is located in a building of tight construction
(See the National Fuel Gas Code, ANSI Z223.1 latest
3.
4.
revision), the boiler area should be considered as a confined space. In this case air for combustion and ventilation shall be provided according to paragraph #5. If there is any doubt, install air supply provisions in accordance with the latest revision of the National Fuel Gas Code.
When a boiler is installed in an unconfined space, in a building of unusually tight construction, air for combustion and ventilation must be obtained from outdoors or from spaces freely communicating with the outdoors.
A permanent opening or openings having a total free area of not less than 1 square inch per 5,000 BTU per hour of total input rating of all appliances shall be provided. Ducts may be used to convey makeup air from the outdoors and shall have the same cross-sectional area of the openings to which they are connected.
When air for combustion and ventilation is from inside

When the boiler is installed in a confined space and all air is provided from the outdoors the confined space shall be provided with one or two permanent openings according to methods A or B. When ducts are used, they shall be of the same cross sectional area as the free area of the area of the openings to which they connect. The minimum dimension of rectangular air ducts shall be not less than 3 x 3 inches or 9 square inches.
When installing two openings, one must commence within 12 inches from the top and the other within 12 inches from the bottom of the enclosure. The openings shall communicate directly, or by ducts, with the outdoors or spaces (crawl or attic) that freely communicate with the outdoors. One of the following methods must be used to provide adequate air for ventilation and combustion.
I. When directly communicating with the outdoors, each opening shall have a minimum free area of 1 square inch per 4,000 BTU per hour of total input rating of all equipment in the enclosure. See

WARNING
ALL INSTALLATIONS OF BOILERS AND VENTING SHOULD BE DONE ONLY BY A QUALIFIED EXPERT AND
IN ACCORDANCE WITH THE APPROPRIATE INSTALLATION MANUAL. INSTALLING OR VENTING A BOILER

APPLICABLE FEDERAL CODES
NFPA 54/ANSI Z223.1, National Fuel Gas Code and NFPA/
ANSI 211, Chimneys, Fireplaces, Vents and Solid Fuel Burning
Appliances. These codes contain information on special gas vents for Category II, III and IV appliances, vent sizing, location, air space clearances to combustibles and safe installation practices. The gas vent installer should be familiar with these
Federal Codes as well as Local Codes and Regulations.
GENERAL INFORMATION GAS VENTS AND
APPLIANCES:
By Federal Codes, gas appliances are categorized by the pressure and temperature of the flue gas vented from the appliance. Category I and II appliances are natural draft (draft hood) vented, with high flue gas temperatures (Category I), and low flue gas temperatures (Category II). Category III and IV appliances are fan forced vents with high temperature (Category
III) and low temperature (Category IV) flue gasses. Appliance efficiency is directly related to flue gas temperature. Higher efficiency appliances remove more heat from the gas, so they will have lower temperature flue products. When flue gas temperatures are lowered, corrosive condensates may form in the gas vent or in the appliance. Condensates may form in Category II, III, IV appliance vents, so special, corrosive resistant venting systems are required for higher efficiency appliances.
!
Vents for Category I appliances may not be suitable for use with Category II, III, or IV appliances because condensate may corrode the vent.
!
WARNING
WARNING
Vents for Category III appliances may not be suitable for use with Category I appliances because flue gas temperatures may be too high.
When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for the proper venting of the appliances remained connected to it. If this situation occurs, the following test procedure must be followed:
REMOVAL OF BOILER FROM VENTING SYSTEM
At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.
1.
2.
3.
Seal an unused opening in the common venting system.
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 condition.
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 dryers and any other appliance not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.
VENT SYSTEM MODIFICATION
4.
5.
6.
7.
Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so appliance will operate continuously.
Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle, or smoke from a cigarette, cigar or pipe.
After it has been determined that each appliance remaining connected to a common venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliances to their previous condition of use.
Any improper operation of the common venting system should be corrected so the installation conforms with the latest revision of the National Fuel Gas Code, ANSI
Z223.1. When resizing any portion of the common venting system, the common venting system should be resized to approach the minimum size as determined using the appropriate tables in the latest revision of the National Fuel
Gas Code, ANSI Z223.1.
12
CONNECTING GAS SERVICE
1.
2.
Connect gas service from meter to control assembly in accordance with ANSI Z223.1 and local codes or utility.
A ground joint union should be installed for easy removal of gas control for servicing. A drip leg or trap must be installed at the bottom of a vertical section of piping at the inlet to the boiler. A pipe compound resistant to the action of liquified petroleum gases must be used on all threaded pipe connections. Check with the local utility for location of manual shutoff valve if required. See
figure #11
.
The gas line should be of adequate size to prevent undue pressure drop and never smaller than the pipe size of the main gas control valve. See chart below.

SEQUENCE OF OPERATIONS
ON A CALL FOR HEAT:
The thermostat will actuate, completing the circuit between terminals T and T.
The R8222C relay coil will energize thus pulling in the relay contacts.
The circulator starts and power is switched to the limit.
If limit circuit is closed the venter motor and TF-2 transformer are energized.
7.
8.
In the event the boiler water temperature exceeds the high limit setting the power will be interrupted to the venter motor, and TF-2 thus interrupting power to the ignition system. Power will remain off until the water temperature drops below the high limit setting. The circulator will continue to operate under this condition until the thermostat is satisfied.
The venter motor starts and develops static pressure.
When the static pressure is reached the pressure switch pulls in completing the circuit between TF-2 and the intermittent ignition control.
Should the air flow (static pressure) be interrupted (example blocked flue, etc.), the pressure switch will sense a drop in pressure, opening the circuit between the ignition system and TF-2. The venter motor will continue to operate until static pressure is reached or thermostat is satisfied.
The intermittent ignition control opens the pilot valve and ignites pilot. After pilot is proven the main burner will ignite.
9.
In the event the flow of combustion products through any part of the boiler flueway becomes blocked, a flame safety roll-out switch will shut off the main burners. If this condition occurs, do not attempt to place the boiler back operation.
10.
When the thermostat is satisfied power is interrupted to the relay coil and the relay drops out cutting power to the circulator, venter motor, and TF-2.

GENERAL INSTRUCTION FOR SEASONAL STARTUP & MAINTENANCE
It is suggested that a qualified service agency be employed to make an annual inspection of the boiler and the heating system. They are experienced in making the inspection outlined below.
In the event repairs or corrections are necessary they can make the proper changes for safe operation of the boiler.
!
CAUTION
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after service.
If the venter has oil cups, lubricate venter motor once a month during the heating season with a few drops of non-detergent motor oil (SAE 20 or 30). Replace the rubber plugs when finished.
!
CAUTION
DO NOT OVER OIL.
BEGINNING OF EACH HEATING SEASON
1.
A.
Before seasonal start-up, it is highly advisable to have a certified service agency inspect the system:
Check the boiler for soot and scale build up in the flues.
2.
B.
C.
Clean the burners.
Check the gas input rate to maintain high operating efficiency.
The service agency should make certain the system is filled with water to minimum pressure (approximately 12 pounds per square inch) and open air vents (if used) to expel any air that may have accumulated in the system.
3.
4.
Check automatic air vents for leakage.
Inspect venting system at the start of each heating season. Check the pipe from the boiler for signs of deterioration and sagging joints. Repair if necessary. Remove the vent pipe from the boiler and check for obstructions.
5.
Clean condensate tee & trap. Periodic cleaning of the condensate collection system is required. When a condensate collection system is installed in a venting system, it is recommended that the cleaning become a part of the annual servicing.
THE PROCEDURE FOR CLEANING THIS SYSTEM
FOLLOWS:
A.
B.
C.
D.
Remove tubing from condensate tee.
Empty all liquid from tubing.
Rinse tubing inside & out in a sink with water.
If tubing cannot be cleaned inside, the tubing should be replaced with the same type and size of tubing.
E.
F.
Replace tubing as described in with water.)
figure #14
. (Fill trap
Visually inspect entire piping system and if any leaks appear, have them repaired as soon as possible. DO
NOT use petroleum based stop leak compounds.
6.
A.
Check venter assembly static pressure as follows:
With the boiler off, disconnect the white compression fitting on the pressure switch.
B.
C.
Connect a slope manometer to the compression fitting with additional tubing.
Turn the boiler on and read suction pressure on the manometer. Reading should be negative (-) .55 ± .05 inches of water column or higher for the 50B thru 150B and negative (-) .65 ± .05 inches of water column or higher for the 200B.
7.
If static pressures are not at the minimum allowable level
(listed above), check vent pipe for obstructions.

J.
Visually inspect the venter assembly for any unusual wear or dirt build up. Clean with vacuum if necessary.
Place a sheet of heavy paper or similar material over the bottom of the combustion chamber and brush down the flue passageways. The soot and scale will collect on the paper and is easily removed with the paper.
Vacuum out base and flueways and reassemble the boiler in reverse order.
Seal flue collector and vent adapter with high temperature silicone. (+400°)
9.
K. Start boiler to ensure proper operating condition.
Keep the area around the boiler clean and free of combustible materials such as gasoline, paints, paint thinner and other such flammable vapors and liquids.
10.
The free flow of combustion and ventilating air to the boiler and boiler room must not be restricted or blocked.
11.
Some circulators require periodic servicing. These circulators usually have oil cups or openings at each end of the motor and one for the shaft bearing. Put about one teaspoon of SAE 20 or 30 non-detergent motor oil in each

opening twice per year. DO NOT OVER OIL. Follow the manufacturers instructions attached to the circulator.
When oil cups or holes are not provided, bearings are either permanently lubricated or water lubricated.
12.
Visually check the main burners and pilot flame at the start of each heating season and again midway through the season.
A.
B.
Check the burner throats and burner orifices for lint and dust obstructions. See
figure #17
.
The main burner flame should have a well defined inner blue mantel with a lighter blue outer mantel. See
figure #18

B.
C.
D.
E.
Turn inner screw (adjustment screw) clockwise to decrease and counterclockwise to increase the pilot flame, see figure #20.
After adjustment, be sure to replace cover screw to prevent possible gas leakage.
The main burners and the pilot burner should be checked for signs of corrosion or scale build up.
Clean main burners and pilot burner with a steel bristle brush.
CHECK GAS INPUT RATE TO BOILER
1.
Maximum permissible gas supply pressure must not be higher and minimum supply pressure must not be lower than what is specified on the rating plate.
2.
A.
To check for proper flow of natural gas to boiler using the gas meter, proceed as follows:
Turn off the gas supply to all other appliances, except the boiler.
B.
C.
D.
With the boiler operating, determine the flow of gas through the meter for two minutes and multiply by 30 to get the hourly rate (in cubic feet).
Divide the input rate shown on the rating plate by the heating value of the gas as obtained from the local gas company. This will determine the number of cubic feet of gas required per hour.
If minor adjustment is necessary, adjust the pressure regulator on the combination gas control. Increase or decrease manifold pressure to obtain gas input required as described on the rating plate. To increase, turn the regulator adjusting screw clockwise or counterclockwise to decrease pressure, see Figure #20.
The manifold pressures are taken at the outlet side of the gas valve.
E. Relight all the other appliances turned off in step "a." above. Be sure all pilot burners are operating.
