Boiler Installation 1 Installation The GT 300 A/II boiler has a bas e frame, although a housekeeping pad is re commended to keep steel par ts out of casual water. Its furnace is closed, so it is not necessary to place it on a fireproof floor, but the floor must be able to bear the weight.
Venting 5. . Boiler Venting & Chimney General Caution & Warning: It is advised and recommended that the heating contractor-professional apply vent materials that are approved and agency listed. Installation of any venting must follow all local codes in conjunction with vent manufacturer instructions and appliance manufacturer instructions. All De Dietrich GT series oil-gas fired cast iron boilers are high performance boilers that could operate under all 4 vent categories as established by ANSI Z21.
5.1 Boiler Venting – Category I & II Typical Layouts and Requirements. Caution & Warning: Improperly sealed venting system could result in carbon monoxide [CO] poisoning; ensure adequate support and fastening of the system. Ensure venting can safely exhaust all flue gases outside in an effective manner. These systems must operate under a negative vent pressure condition that is stable. Warning & Cautions for Co-Venting: Co-venting with other appliances shall conform latest ANSI Z223.
5.2 Boiler Venting – Category III & IV Vent Systems Typical Layouts and Requirements. Caution & Warning: Improperly sealed venting system could result in carbon monoxide [CO] poisoning; ensure adequate support and fastening of the system. Ensure venting can safely exhaust all flue gases outside in an effective manner. These systems must operate under a positive vent pressure condition that is stable. Warning & Cautions for Co-Venting: Co-venting with other appliances shall conform latest ANSI Z223.
5.3 Boiler Venting – Side-Wall or Direct Vent Systems Typical Layouts and Requirements. Caution & Warning: Improperly sealed venting system could result in carbon monoxide [CO] poisoning; ensure adequate support and fastening of the system. Ensure venting can safely exhaust all flue gases outside in an effective manner. These systems must operate under a positive vent pressure condition that is stable.
5.4 Boiler Venting – Side-wall or Direct Vent Systems Sizing Tables & Vent Safety Device • Vent termination must be a TEE type, follow warning regarding termination locations. Do not include the termination TEE length in the vent length calculation. • Venting shall be sloped, so any condensation developed will drain through the condensate TEE fitting Minimum vent length [equivalent] 5 ft. [1.5m] • Maximum number of 90° elbows = 2 or 3 45° elbows, each 90° elbow is equivalent to 10 ft.
5.5 All Side-wall and direct Vent termination locations installation precautions: Warning/Caution: In all cases avoid potential vent termination locations where excess debris or snow could accumulate and bock the vent termination to any degree. Minimum clearance of 4 ft. [1.22m] horizontally from, and in no case above or below, unless a 4 foot [1.22m] horizontal distance is maintained, from electric meters, gas meters, regulators & relief equipment.
6 Dimensional information required for connection of the boiler 15 5 "5 The boiler must be connected to venting system that will safely and effectively discharge all flue gases to the outside in an effective manner. /16 "11 /16 Consult local and national codes regarding the boiler breeching and chimney sizing.
Electrical 1 Wiring Wiring in accordance with the requ irements of the authority having jurisdiction or, in the absence of such requ irements, with the Canadian Electrical Code Part 1, CSA C22.1, Electrical Codes. 2 Wiring procedure De Dietrich boiler suggested field wiring procedure.
FOR YOUR SAFETY READ BEFORE OPERATING If you do not follow these instructions exactly, WARNING: a fire or explosion may result causing properly damage, personal injury or loss of life. A. This appliance does not have a pilot. It is equipped with an ignition device wich automatically lights the burner. Do no t try to light the burner by hand. B. BEFORE OP ERATING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
Maintenance 1 Boiler It is no t ad visable to drain an in stallation, ex cept in ca se of absolute necessity. Check the water level of the installation and top it off if necessary, avoiding a sudden inlet of cold water in the hot boiler. Check for system leaks. Professional water treatment is recommended. The good performance of the boiler depends on cleanliness. Cleaning the boiler must be carried out as often as required and at least, as for the flue once a year.
- open the sweeping door (upper door) by unscrewing the 4 lock nuts. - also brush the convection baffles and the front face, - remove the convection baffles, - if possible use a vacuum cleaner, - using the brush supplied, carefully sweep the 6 flue sections, - put the convection accelerators back in place (pay attention to their direction), - shut the door.
Service and maintenance schedule `Require annul system inspecti on of the heating boiler, burner and controls by qualified service personnel, `Heating sys tem c heck for safe ty control functions, system pressure, leaks, combustion and ventilation air should be done on a monthly schedule. Extended Shutdown Periods If the system is to be shutdown for any extended period of time, please follow these steps: 1. Shut off all pumps 2. Cap off venting of boiler at the boiler collars 3.
