1) Refer to the figure below for the foundation. Construct on the ground the hatched portion of the foundation completelyas shown below.2) Install the unit on a level ground.

For details,refer to“Installation manual for vibration-proofbase”.GHC-HMT(5) Fuel gas pipingOWARNING¡ After connecting the fuel gas pipe, be sure to take the gas leakage test.¡ For the gas leakage test, use soapy water or the gas leak tester. Never attempt to take the gas leak test of the flamecolor reaction since it is very dangerous.OCAUTION¡ Support the fuel gas pipe as necessary. If any pipe is poorly supported, the stresses will be concentrated on the pipe,possibly causing the pipe to be cracked.¡ Use the metallic fuel gas pipe, and be sure to use the outdoor type reinforced gas hose or the low-pressure hose withthe fitting for liquefied petroleum gas. Never use any flexible pipe.(a)Fuel gas piping layoutUnit: mmPressure output port tapFuel inlet (25A)Main valveOutdoor unit260154DrainStrainer Outdoor type reinforced gas hose or low-pressurehose with the fitting for liquefied gas(6) Exhaust gas drain pipingOWARNING¡ Never connect the exhaust gas drain water of the outdoor unit to the water pipe of the drain water of the indoor unit.Otherwise, the exhaust gas will enter the indoor room.¡ Since the exhaust gas drain water of the outdoor unit is at the high temperature, never touch the water, or it can cause burns.OCAUTION¡ Discharge the exhaust gas drain into the drain channel, gutter or other which is released to the open air. Never placeany drain hose on the floor surface.* If it is specially exposed on the roof, extend the drain pipe to discharge the drain to the rain water drain port (roofdrain). If any exhaust gas drain is discharged to on the floor surface, it will sometimes damage the waterproof sheetand stain the concrete surface.Notes (1) Use the hard vinyl chloride pipe to extend the drain.(2) Be sure to slope the pipe downward.(3) Be sure to release the exhaust gas drain to drop into the concentrated pipe, gutter or similar.(4) Carry out the work to prevent exhaust gas drain from scattering.(5) In cold districts, exhaust drain piping may freeze, install heater to prevent any blockade.6
