      What questions should you ask when sizing/fitting a heater?
      - Will the heater be installed indoor or outdoor?
      - Will it be installed with natural gas or propane?
      - Electronic Spark (LLD) or Pilot Light (LLG) ignition?
      What is a heat exchanger?
      - The heat exchanger is the component with finned tubes, coils or plates that absorb heat into the water from inside the exchanger itself. It is made on one solid piece of copper. If it is leaking, it is due to improper water balance.
      Why won’t the pilot light?
      - Could be due to low gas pressure, inadequate air supply or improper venting. Make sure gas is turned on; with propane, make sure the tank has fuel. Also check for water run-off from roof or sprinklers. Check to make sure the heater pilot tubing is intact and not clogged.
      Why won’t the heater reach the desired temperature?
      - The thermostat may be set too low. If the heat loss is greater than the heater input – the heater may be too small, outside air temperature is too low, or your heater may have inadequate gas supply. All heaters have high limit switches to prevent overheating. A faulty high limit switch could shut off the heater, or the problem could be that the heater is truly overheating, perhaps from improper exhaust.
      Why is my heat exchanger leaking?
      - Overly acidic water levels or water had frozen in exchanger – replace heat exchanger and maintain proper water chemistry & drain in winter.
