INTRODUCTION
The mexico hE range of boilers are fully automatically controlled,
floor standing, low water content, balanced flue, fanned,
condensing gas boilers. They have full modulating central heating
outputs of :
hE15 8.8 kW (30,000 Btu/h) to 14.6 kW (50,000 Btu/h).
hE18 8.8 kW (30,000 Btu/h) to 18.2 kW (62,300 Btu/h).
hE24 8.8 kW (30,000 Btu/h) to 23.4 kW (80,000 Btu/h).
hE30 10.6 kW (36,200 Btu/h) to 30.1 kW (102,700 Btu/h).
hE36 10.6 kW (36,200 Btu/h) to 37.0 kW (126,200 Btu/h).
Due to the very high efficiency of the boiler a plume of water
vapour will form at the flue terminal during operation depending on
external conditions.
The boiler casing is of white painted mild steel with the user
controls capable of being mounted remotely from the boiler, if the
option is required.
The heat exchanger is of cast aluminium.
Artificially softened water must NOT be used.
A pre-piping frame is provided to allow system and gas
connection to be made prior to boiler installation.
Note.
These boilers cannot be used on systems which include gravity
circulation.
The boilers are suitable for connection to fully pumped, open
vented or sealed water systems. Adequate arrangements for
completely draining the system by provision of drain cocks MUST
be provided in the installation pipework.
