Introduction and Dimensions

Selectra SERIES 14 electronic gas flame modulation systems are designed primarily for make-up air heating, as components of direct fired equipment. They may be field installed on existing equipment or specified for new equipment installation. Natural, manufactured, mixed, LP and LP gas air mixture are compatible gases.

The systems utilize Modulator or Modulator-Regulator valves. Amplifiers are available with adjustable low-fire start duration, and with integral or remote temperature selection. A discharge air temperature sensor is mounted within a mixing tube housing.

Optional - a room override thermostat provides space temperature control by raising the discharge air temperature to a pre-selected point - when used in conjunction with the remote temperature selector. Optional - an inlet air sensor (and mixing tube) provides inverse change in discharge air for each degree change in inlet air - when installed in a convenient duct location upstream of the burner. Optional - a dual temperature selector replaces TD114 to provide dual control for door heaters, or other applications such as paint spray booths (TD214_ or _X, or AD1214_).

MIXING TUBES

Specifications

Power Requirements: 24 VAC, 50/60 Hz Class II transformer NOTE: Transformer secondary must not be grounded in any portion of the circuit external to a Maxitrol amplifier. If existing transformer is grounded, a separate isolated transformer must be used. Electrical interference may effect performance and/or damage equipment. Ambient Limits:

Operating.....-40

Non-operating.....-50

Gases: Suitable for application in natural, manufactured, mixed gases, liquefied petroleum gases and LP Gas Air Mixture piping systems.

Vent: M411, 511, 611.....vertical vent outlet 1/8" NPT - 12A06

installed

MR212.....two vents located in upper housing, both equipped

to 125o F / -40o to 52o C

to 185o F / -46o to 85o C

Installation of Components

Control wires connected to the Override Stat, Discharge Air Sensor, or Remote Temperature Selector must not be run close to or inside conduit with power or ignition wires. Doing so may cause the unit to function erratically or may destroy the amplifier. If shielded wires are used, shield must be insulated and grounded at the amplifier location only.

with vent limiting means

Pressure Limits:

Maximum Discharge Pressure (M411, 511, 611).....7" w.c. /

17 mbar

Static Pressure Rating (M411, 511, 611).................5.0 psi /

345 mbar Maximum Operating Inlet Pressure

M411, 511, 611.....1 psi / 70 mbar

MR212.....5.0 psi / 345 mbar

Maximum Emergency Exposure*

M411, 511, 611.....3.0 psi / 210 mbar

MR212.....12.5 psi / 862 mbar

* May not function properly at this pressure, but will suffer no internal damage

Remote (or Dual) Selector: Install in control cabinet or other chosen location. NOTE: Suffix letters must match, e.g. TS114A must be used with TD114A. For wiring runs longer than 200 ft. substitute ES261-1/ES261-2 for TD114. The ES261s are a 2-piece version of the TD114. ES261-1 is a temperature setting dial only, ES261-2 must be mounted at furnace location.

Wiring Run: If control wiring is inside conduit with

line voltage wiring, use shielded cable up to 100 ft.

For best results up to 200 ft., run control wiring in

separate conduit. For longer runs see Remote Selector below.

Discharge Temperature Sensor / Mixing Tube Assembly: sensor housed in mixing tube, install in

discharge air stream.

Optional:

Dual Temperature Selector: see preceding Remote/Dual selector.

Amplifier / Amplifier-Selector: contains the wiring terminals and sensitivity adjustment - install in any convenient location that is protected from the weather and contaminated atmosphere.

Room Override Stat: mount in heated area not in direct path of discharge air stream.

Inlet Air Sensor: install in convenient location upstream of burner, in intake air duct.

Typical Gas Trains

Modulator (M) or Modulator-Regulator (MR) Valve: Mount in upright position in horizontal run of pipe, downstream of other controls - a separate gas pressure regulator must be used with any modulator (M) valve.

MR Valve: Modulator-regulator valve

M Valve: Regulator upstream of modulator valve
