Resumen del manual
j Select Circulator versus Zone Valve The flow of hot boiler water to the BOILER MATE™can be controlled with either a motorized zone valve or a circulator. 1. Zone valve (system flow of 4-8 gpm). If a zone valve is to be used, a minimum flow rate of 4 gpm with all zones in use is required with a maximum of 8 gpm with only the BOILER MATE™ in use. Be sure the zone valve chosen has a maximum pressure drop (Cv = 4) when fully opened. 2. Separate circulator. The recommended way to provide adequate flow through the BOILER MATE™ heat exchanger is to use a separate dedicated circulator with a minimum flow rate of 4 gpm (10 feet of head minimum) and maximum flow rate of 8 gpm. This option may be used even though the heating system utilizes zone valves. j All installations require a low-water cut-off or automatic fill valve on your boiler system to reduce the risk of boiler water loss. j Steam boiler installations require a low-water cut-off which is also required by most codes. j Installation of a vacuum breaker is required to prevent damage to the BOILER MATE™ when drained. -4 3. REQUIRED COMPONENTS AND ACCESSORIES CHECKLIST TD-7Z, TD-41Z, TD-7ZDW, TD-41ZDW COMPONENTS CHECKLIST The following is a checklist of components required for proper installation of these BOILER MATE™ models, both Priority and Non-Priority: A. Separate circulator • 1 each - circulator (4-8 gpm) • 1 each - positive shut-off weighted check valve B. Use of heating system zone circulator • 1 each - zone valve C. Also Required: • 4 each - unions • 4 each - shut off valve • 1 each - vacuum breaker • 1 each - T & P relief valve (included) • 1 each - A THERM-X-TROL® expansion tank -REQUIRED IF a Back flow preventer, check valve or pressure reducing valve is installed anywhere between the BOILER MATE™ and the city main. • As needed - pipe dope or Teflon tape • Do not forget an EXTROL® and thermal expansion - an expansion tank is required on the boiler side of your system. If a steel hydropneumatic tank is in place, AMTROL recommends replacing it with a properly sized EXTROL® expansion tank. Otherwise, significant heat transfer problems can occur by causing air to be trapped in the heat exchanger. If the boiler system has an EXTROL® expansion tank and the boiler temperatures are being changed, resize the EXTROL® expansion tank. -5 4. INSTALLATION INSTRUCTIONS FOR FORCED HOT WATER, CLOSED HYDRONIC HEATING SYSTEMS A. General Installation Requirements 1. Do not "short circuit" the boiler Do not connect boiler supply and return lines to the same section or in the same flow circuit in a boiler, because the boiler water returning from the BOILER MATE™ will "short circuit" and exit the boiler too cold for proper heat transfer. 2. Avoid high flow domestic water recirculating loops If a recirculating loop is necessary consult applicable Code requirements. A flow of no more than 1/2 gpm is all that is generally needed for temperature maintenance at the furthest hot water fixture. Any flow greater than 1/2 gpm will result in excessive heat loss and reduction in performance. 3. Locating Unit Do not locate this product where leaking and flooding could cause damage to surrounding property. The BOILER MATE™ should be located in an area where water leakage from the tank or connections will not result in damage to areas adjacent to the application or to lower floors of the structure. When such a location cannot be avoided, a suitable drain pan must be installed. The pan must be connected to a drain. The installation location for this unit should also be chosen to comply with the following required and recommended dimensions for clearance and accessibility: Clearance from Combustible Surfaces This unit is design certified by the C.S.A. for installation on combustible flooring and in alcoves, closets, etc. The minimum clearance dimensions from combustible material is as follows: (See dimensions given facing units) Clearance From Combustible Surfaces LEFT SIDE ...........10" REAR .....................1" RIGHT SIDE.........10" FLOOR ..................0" TOP......................30" FRONT ..................1" Recommended Clearance for Servicing LEFT ....................10" HEAD ROOM ........30" RIGHT..................10" REAR .....................1" FRONT.................30" 4. Instructions for reversing unit: The unit is designed to be reversible, i.e. depending on the particular installation area, the BOILER MATE™ can be rotated 180° for easier connection to the boiler and cold water supply. All units are shipped "left-handed" with all connections (boiler, cold water supply) on the left side of the unit. If, for ease of installation, it is necessary to have the connections on the right, the following steps should be taken: 1. Carefully remove the front panel (remove top screw and unhook from stand). 2. Move the access panel/electronic control assembly to the opposite side of the BOILER MATE™. 3. Remove the ground screw from the BOILER MATE™ stand and save. 4. Proceed wit...
