Munchkin Gas-Fired Hot Water Circulating Heater Part 12. START-UP Procedure, Condensate Removal

GAS-FIRED HEATER Installation Manual

PART 11. START-UP PREPARATION (CONTINUED)

G. CONDENSATE REMOVAL

1.The Munchkin Contender is a high efficiency condensing heater, there, the unit has a condensation drain. Condensate is nothing more than water vapor, derived from combustion products, similar to an automobile when it is initially started. The condensation is slightly acidic (typically with pH of 3 to 5) and must be piped with the correct materials. Never pipe the condensate using steel, copper, brass or other materials that will be subject to corrosion. Plastic PVC or CPVC pipe are the only approved materials. A condensate filter, if required by local authorities, can be made up of lime crystal,s marble or phosphate chips that will neutralize the condensate. This may be done by the installer or you may purchase a condensate neutralizer from Heat Transfer Products, Inc. (P/N N1100)

2.The Munchkin Contender is equipped with a ¾ pipe connection that runs the condensation line to a local drain. It is very important that the condensate line is sloped away from the heater and down to a suitable inside drain. If the condensate outlet is lower than the drain, you must use a condensate removal pump, available at Heat Transfer Products (#554200). This pump is equipped with two leads that can be connected to an alarm or another type of warning device to alert residents of a

condensate overflow, which, if not corrected, could cause property damage.

3.If a long horizontal run is used, it may be necessary to create a second vent to prevent a vacuum lock in the condensate line. Do not expose the condensate to freezing temperatures.

4.Do not expose the condensate to freezing temperatures.

5.It is very important you support the condensation line to assure proper drainage.

H.FINAL CHECKS BEFORE STARTING MUNCHKIN CONTENDER

1.Read Startup Procedures within this manual for proper steps to start heater. (See Startup Report to record steps for future reference.)

2.Verify the heater and system are full of water and all system components are correctly set for operation.

3.Fill condensate trap with water.

4.Verify electrical connections are correct and securely attached.

5.Inspect intake piping and exhaust piping for signs of deterioration from corrosion, physical damage or sagging. Verify intake piping and exhaust piping are intact and correctly installed per Venting section and local code.

PART 12. START-UP PROCEDURE

FOR YOUR OWN SAFETY READ BEFORE OPERATING

1.This appliance does not have pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand.

2.BEFORE OPERATING 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.

WHAT TO DO IF YOU SMELL GAS

•Do not try to light any appliance.

•Do not touch any electric switch; do not use any phone in your building.

•Immediately call your gas supplier from a neighbor's phone. Follow the gas suppliers' instructions.

• If you cannot reach your gas supplier, call the fire department.

3.Turn on gas shutoff valve (located inside of the Heater) so that the handle is aligned with the gas pipe. If the handle will not turn by hand, don't try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion.

4.Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

5.The Munchkin Contender Heater shall be installed so the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during appliance operation and service (circulator replacement, condensate trap, control replacement, etc.)
