Oil Burner and Controls Start-Up and Adjustment

INDOOR CHIMNEY VENTED BOILERS

Instruction manual enclosed in burner carton must be followed in regard to start-up and adjustment

1.Standard Beckett AFG or CF375 Oil Burner

A Beckett model AFG oil burner is normally supplied with boilers to be fired at 2.00 gph or less. It is equipped with an F3 flame retention head, the size most commonly used. It is possible the head must be changed to match the nozzle firing rate required, and it is recommended the installer carry a complete assortment of Beckett flame retention heads. When head ratings overlap, a smaller head with air shutter fairly well open will generally provide better combustion than a larger head with air shutter near closed. See head size selection chart on page 16. For Beckett burners at firing rates above 2.00 gph, a Beckett model CF375 burner is required, and is supplied if specified by purchaser.

2.Optional Riello 40 Series Oil Burner

Riello 40 series oil burner is optional. Model F5 is used for firing rates from 0.90 to 1.50 gph, and Model F10 is used for firing rates from 1.60 to 3.00 gph. Model F5 or F10 is supplied if specified by purchaser. For firing rates below 0.90 gph, a Model F3 is required, and must be purchased from a Riello distributor.

SUGGESTED NOZZLES, HEADS, AND PRELIMINARY SETTINGS FOR VARIOUS FIRING RATES AND BURNERS ARE SHOWN ON PAGES 40 AND 41.

3.On knockdown boilers, the burner is not supplied with a nozzle. The correct nozzle is the smallest which will do the job properly. Long continuous runs with minimum starts and stops conserve the most energy. The nozzle which provides the highest C02 with the least smoke for a particular application is always recommended. Beckett Oil burners are supplied with pump pressure set at 140 psi. Nozzle output will be approximately 18% greater than that at 100 psi. Pump pressure on Riello burners should be adjusted according to settings on page 41.

4.WARNING: Too low a firing rate can cause excessive condensation within the boiler and chimney resulting in severe rust and corrosion. A piping by-pass is recommended to minimize this problem. See page 14.

5.If Beckett AFG burner is to be fired at less than 1.00 gph, it is possible that a low firing rate baffle will be required. For firing rates not specified on page 40, see chart below on which an “x” indicates that a baffle is necessary. See also instruction sheet with baffle in burner carton.

6.Using three acorn nuts, studs and washers from hardware package, fasten burner to mounting plate.

7.Mount L8151 control on boiler jacket above and to the right of burner using sheet metal screws in holes located in jacket. Wiring harness is provided. When well is used at the rear of a larger boiler, it might be necessary to relocate the control with longer wiring not provided.

8.If the boiler is equipped with a tankless coil, insert well for the L8151 remote bulb in coil plate. Run capillary tube through sight glass opening in jacket.

9.If a tankless coil is not used, install 3/4" well and bulb with a bushing either in the 1 1/2" supply opening opposite the one used to feed radiation, or in a reducing tee in the 1 1/2" supply opening that actually feeds radiation.

10.Wiring diagram is found on page 16. To avoid excessive condensation, do not use a two-stage thermostat or other fuel saving devices or techniques without first contacting the factory.

11.BEFORE MAKING CONTROL ADJUSTMENTS, verify that all fuel, water and electrical connections have been made in accordance with the regulations of the National Fire Prevention Association, the National Electrical Code and/or local regulations.

12.See page 14 for control settings.

13.Start-Up and Adjustment: Start and adjust burner according to manufacturer’s instructions contained in burner carton or included with packaged boiler, and pay special attention to the following:

a.As the name suggests, this boiler is designed to produce the ultimate in useable heat from a gallon of fuel oil. To adjust the air-fuel mixture by eye is to waste fuel and create soot.

b.Repeat - Do not adjust air by eye. Any time air adjustment or oil rate is changed, combustion must be checked with instruments.

c.With chamber fully warmed up, find the highest C02 level at which zero smoke can be maintained. Then add extra air until C02 falls off 1%. Final setting should be at least 11% C02. If unable to obtain that reading, check for internal oil leaks, incorrect flame retention head or a faulty or incorrect nozzle. (See charts on page 16.) Draft will vary as air is adjusted. It should be left at as near zero as possible at breeching.

Complete installation must be made in accordance with the requirements of local authorities and the National Fire Protection Association
