Installation

Wiring and Electrical

Following the wiring diagram, run all wires to their designated connections. Save the main power for the last hook-up, and leave the breaker in the off position. The sensor wires attach to the A350 Controller on the terminals marked “sen” and “com”. Make sure the sensor is submerged fully into the well and secured with the set-screws.

Setting The Aquastat

Inside the A350 control, you will see a square jumper, and a differential dial. Be sure the jumper is in the “Heating” position. The differential dial is set to determine how low, below the temperature set point, you want the water temperature to go before the Automatic Draft Control opens. A good initial setting for this dial is 5°. Be sure the 120V wires are attached to the common and the normally open terminals, and replace the cover. The external dial is set for the water temperature you wish to maintain, a good setting is 180°.

Inside the Y350 control, ensure that your wires are connected to the 120VAC terminals, and replace the cover.

Inside the S350 control, which is used as overheat protection, you’ll see two dials; offset, and differential. There is also a jumper which, in this case, gets placed in the “cooling” position. The offset dial sets the number of degrees above the A350 setpoint that you want the overheat dump to activate. A good set point would be 20°. That would mean that if the water reaches 200°, using the A350 setpoint of 180°, the S350 would close it’s contacts and energize the overheat dump zone. The differential dial sets the point that the overheat dump would stop. With the differential set at 15°, using the temperatures above, the circuit would re-open, stopping the overheat dump at a water temperature of 185°. The 120V wiring is attached on the normally open and the common position. The normally closed position is not used.

Re-install the covers onto the three Controls.

Optional Items

There is a domestic hot water coil available for your Trident Boiler. The coil installs in the front of the boiler, and allows your domestic water to be heated by the heating system water. Install the coil now, by removing the round plate and replacing it with the coil and it’s round plate. Be sure to tighten the bolts evenly, to ensure a good seal.

If electric back-up is desired, install now. There will be two additional control boxes to add to your aquastat, which will require the use of a longer din rail. The two heating elements will install into the front of the boiler as shown in Fig. 1

Venting

The Harman Trident Boiler must be installed into a chimney approved for solid fuel burning appliances. In the U.S., the boiler must be connected to; (1) a prefabricated chimney complying with the requirements for Type HT chimneys in the Standard for Chimneys, Factory Built, Residential Type and Building Heating Appliances, UL 103. Or; (2) a code approved masonry chimney with a flue liner. In Canada, with prefabricated chimney systems tested and listed to the High Temperature Chimney Standard ULC S-629, or with a code approved masonry chimney. The minimum recommended height for any chimney is 16 ft. (4.8m) above the flue collar. Do not reduce flue diameter. Nominal size flue is 8 X 8 in. or equivalent, up to 8 X 12 in. Codes also require that the chimney must extend a minimum of
